Change my GPU status

Hi guys got a little problem here

I’ve got 2 gpus in my system rx 570 and rx 590
I’ve got 1 ssd with fedora on it using the 570 and another running Win10 for gaming and I’d like for windows to use the 590 but I can’t manage to set it as the main gpu it’s listed in the device manager without any apparent problem It also appears in msi after burner and in amd radeon software where the RX570 is listed as PRIMARY/MASTER and the RX590 as LINKED/DISCRETE how can I change those status?
Thanks

PS pc hardware :

CPU 2950x
MB MSI MEG CREATION X399 (UEFI updated)
GPUS RX 570 and 590
