yes you can use the same set to follow/fixed method for gaze. you also can use gimmicks for both neck and gaze, go to "add>item>scroll down for hooh A>hooh gimmicks" or press (control+space) to open the item search and look for "hijack look" gimmick, you have to parent it to the character "glasses" component and it will always make that character looking that way, but since it will also move with the parent character, you will need to attach it to a different object using the "node constraints" plugin. it is a little bit more advanced but if you wish to try it this is how:
[Guide] how to use hooh's "Hijack look & neck" gimmicks (Beginner)
load the look hijack item and then expand the character components at the "work space" on the right, then expand the "face" components and click once on "glasses"m it will turn green, then click on the "look hijack" item while holding (control) on your keyboard, then click on "parent" at the bottom of the menu, this is how to parent two objects via the work space. just note that the item you click on first will act as a parent to all other items you select while holding control later on. if you wish to un-parent an item/s select by clicking on them on work space and then click on "release".

you will notice that the "glasses" component now contains the hijack item and it should look like this:

next, select the root component of the character on the top and go to anim>kinematics>gaze and set to follow, now wherever you move that blue hijack, the char's gaze should follow, but moving the character, or tilting the head/neck will also move that hijack ball along (which is not what you are looking for) so since the hijack is a separated studio item (unlike the "adjust" gaze function) you will be able attach that blue ball to other objects/characters using another method like the node constrains plugin.
next load another object or character of your liking and lets attach the look hijack ball to it, i will use a simple object like a cube just to keep this example simple.

while that cube is selected from work space, press (CONTROL+N) to load the node constraints plugin, then click on "IK" tab on the plugin menu and highlight the root node by clicking on it and click on "set as parent". a green small circle should appear on the object.

then select the look hijack from the work space, move it close to the cube we added, then select it's IK root node from the plugin menu and click on "set as a child". you should see a small red circle. then, check the "posistion" and "rotation" attachment properties from the top and click on "use current" for each. when done, click on "add new" below, now the blue hijack ball is attached to the cube. you should notice a purple line connecting both the green and red circles when clicking on the attachment from the middle box.

now you can select the cube and move it around and test the character's gaze, then tilt/rotate the character's head and nick, it should keep following that cube no mater what direct the neck is at, because the hijack ball is allso attached to it and won't move along. this will allow you to pose the neck and gaze separately. it will help you creating a fixed point where the character's gaze focusing on no matter where they are located or moved to.

you also can do the same with the "hijack neck" gimmick, but instead parenting to the glasses component, you will have to use the "neck" sub component.
View attachment 963316
you also can attach it to the same cube item or another one to gain more control over both neck and gaze rotation as pleased.
Conclusion:
i find those useful when you want to make the character keep looking or facing another fixed object or character during an animation, other gimmicks can be used with the same technique to point them toward fix location as well.
