Hi, danke für deine Antwort, meinte mit dem Board eigentlich das MSI MPB X570 Gaming Plus, sorry.
Hier die IOMMU Ausgabe:

habe das system mit dem "splash" aus dem archwiki Eintrag ebenfall eingetragen, ergibt die selbe ausgabe.
Wie ist das nun zu interpretieren?
Hier noch mein /etc/default/grub File (wo ich die Änderung permanent setzen könnte):

AMD-Vi kann ich im BIOS aktivieren, siehe Bild im Anhang.
Wenn ich GRUB_CMDLINE_LINUX="amd_iommu=on" nun auch im Bootloader(Manager) Grub aktiviere, sieht die Sache wie folgt aus:
