When using open source drivers offloading should be automatic depending on demand. You can make it explicit with DRI_PRIME=0 or DRI_PRIME=1. You’ll have to check which is which.
Two more things that came to mind. If you want to use another desktop environment than gnome (default), you should be aware of spins: fedoraproject.org/spins/
Spins work against the same repositories, they just come with other sets of packages preinstalled.
Also, you said you’re using amd gpu. Fedora has the drivers for that out of the box. But due to fedora’s strict FOSS policy, some hardware acceleration features are stripped out of the amd driver. I mentioned you can get the unstripped drivers from rpmfusion. That is detailed here: rpmfusion.org/Howto/Multimedia
Those packages work together with the drivers from the official repos. They can get out of sync. That never happened to me, yet. But if an update mentions some conflict with mesa-*, just don’t do that update until that conflict disappears. If you ever run into the issue you can also undo the last update with the dnf history commands.
