Group policy to restrict usb port access to domain users but to excluded admins

Hello Expert,

I have a group policy configure to restrict Usb port access ( see attachment ).
Because this is computer policy I found that by unchecking do not apply policy to admins
has no effect
The policy work fine but the downside is admins are affected also.
Is there any other  group policy I can use to achive the above
but exclude admins.


The final picture  should be, any admin should be able to access his/her flash drive  on any workstation but an ordinary domain user should be denied.

Thanks
