You can change Group Policies by opening Group Policy Editor first. You can open it by following these steps:
Log in an administrator account. If you are already logged in as an administrator, proceed to step 2.
Press Windows + R to open Run.
Type gpedit.msc and press Enter.
After opening Group Policy Editor, you can now make the necessary changes that you want.
Should you have more concerns, feel free to post.
