Enabling ASPM on Epyc motherboards

I have an AMD 8224P on a Gigybate ME03-PE0 motherboard and I would like to enable ASPM but I can’t find the option in the BIOS. It’s listed in the manual but it’s also not visible there in the screenshot. Do I have to set another option first?
Trying to activate it with pcie_aspm=force leads to crashes.
The BIOS should be the same for other Epyc motherboards? So maybe somebody can help me as I didn’t get an answer from Gigabyte for a week.

Udually aspm is a sepatate option. Might need to email support

Thanks for the fast reply! Looks like I just have to wait even longer for the slow Gigabyte support.

Completely useless answer after 3 weeks :sweat_smile:
