Possibility to use non-virtio network adapter with Ubuntu cloud-init image?

As the title says - is there any possibility to use a different network adapter type than virtio with the Ubuntu cloud-init image?
Any other (e1000, vmxnet3, rtl8139) aren't detected, as the respective modules aren't part of the image.

I realize this is less of a Proxmox VE and more of an Ubuntu question, but wondering if there is any way to make use of these types (short of compiling from source, which I would rather not do).

I looked around for a corresponding linux-modules or linux-modules-extra for my kernel version (5.15.0-1029-kvm), but:
- the plain linux-modules-5.15.0-1029-kvm doesn't have any relevant driver
- the linux-modules-extra-5.15.0-1029-kvm doesn't even seem to exist in the Ubuntu repo; I did check the -azure version and that one has no relevant drivers either.

I am trying to troubleshoot a rather weird behavior (see my other post) and thought of changing the guest adapter type - seems like a dead end though.
