There is a page at https://thinkstation-specs.com/thinkpad/p1-gen-4-2021/ which appears to list some specs. Also a PDF at https://psref.lenovo.com/syspool/Sys/PDF/ThinkPad/ThinkPad_P1_Gen_4/ThinkPad_P1_Gen_4_Spec.pdf

Have you tried updating to the latest bios? That might help if there are any relevant bug fixes.

I would follow the advice of Gastón and install the kernel from chimaera-backports as it will be much simpler than trying to upgrade to daedalus.

https://www.devuan.org/os/packages

Add the backports repository to apt sources and then run

apt-get update && apt-get install -t chimaera-backports linux-image-amd64
