The correct title would be Revoke document generation permission from CLM Viewers 

Hello @MatheusAlcantara,

So you wanna restrict or we can say hide CLM viewers the generate the document option in the “Action Menu” right?
If yes then you have to follow 2 tasks.

1. Create the “Group” and add all the CLM viewers in the group.
2. Go to the “Navigation & Action” in CLM admin.
   1, Select the group you created in “Who is this for?”
   2. select “User navigation Header” in “What Are you Customizing”
   3. Go to the “Action Menu” and turn off the button of configuration name.
   4. Click Save.

Attaching the Screenshot for the reference to follow the process.
 

Thanks! Mark it “BEST” if you find it right.
