@IntuneUser Thanks for posting in our Q&A.
Of course, you can. I have done the test in my lab. I will share you more details.
Step1: I create a device group that only includes windows devices.
Step2: I create a user group that I want the user in this group only can see windows devices.
Setp3: I create a scope tag called "windows scope tag" in Tenant administration > Roles > scope tags. In this "windows scope tag", I add the windows device group under "assignments".
Setp4: I create a custom role called "windows role" in Tenant administration > Roles and enable the feature what I want and add "windows scope tag".
Step5: I create a role assignment.
Stpe6: When I use the target user signing in intune portal, I can only manage windows devices and I can't see other platform devices.
Hope it will help.
