Can not access terminal via network nor display nor rescue mode

[emircanerkul]

After i blocked myself via wrong firewall configuration i can not access terminal.

Also tried rescue boot but it also stucks.

I was blocked my GPU sake of passthrough for gaming, this might be the case.

Any idea how can i restore my system?

Thank you.
