SU2 Beta - No FSR 4 available on AMD Adrenalin

Graphics card: AMD RX 9070 XT
Driver: Adrenalin 25.3.1

Issue:
After activating FSR 3 in in-game graphics settings the AMD Adrenalin software doesn’t unlock the FSR 4 switch, respectively the MS2024 AMD game profil doesn’t even show the entry from the start.
The assumption is, that FSR3.1 has been implemented.

Has FSR3.1 been implemented or just ‘3’ ?
If yes, has AMD to whitelist the msfs2024.exe ?
(It’s not listed on amd.com/fsr yet).

The following image shows the expected behaviour.
In my case the FSR 4 entry doesn’t even show up, only in global graphics settings and there it doesn’t do anything.

Update:
According to an AMD FSR preview list MSFS2024 is listed with FSR 3.1 available* (*depending on the release)

Update 2:
Same behaviour with SU2 final release 1.4.20.0 and Adrenalin 25.5.1 .
