Minisforum HM90S - PM8 - issues with network and shutdown

Hello all,
I'm using a Minisforum HM90s that I purposely bought to put Proxmox and use it as my home lab.

One of the features I was keen to use was the double LAN ports (1x 2.5Gb and 1x 1Gb) but both are giving me issues.

Current setup:
* Virtual Environment 8.0.4
* Kernel 6.2.16-10-pve

* cannot get IP in any of the LAN ports
* shutdown/reboot needs to be forced via hardware button.

I`m able to use proxmox with an USB ethernet connection.

along the way I also found I had to add the following lines in the grub

Setup default grub for immo
Set UEFI to SVM = Enabled and IOMMU = Disabled
Install OS
Edit grub.cfg
add "amd_iommu=force_enable iommu=pt" to the DEFAULT LINUX line.
Save and recompile grub.
Enter UEFI and changed "IOMMU=Auto" ('Enabled' seems to cause some problems)
Save and reboot
OS should run fine, virtualization works as expected.

Can someone help me understanding what is going on? I've seen in the forum that if I could use the kernel 5.11, some of the issues would be solved. but when I try to run the following command I get this:

# apt update
# apt install pve-kernel-5.15

E: Unable to locate package pve-kernel-5.15
E: Couldn't find any package by glob 'pve-kernel-5.15'
