Install proxmox with zfs to mirrored nvme drives leaving space for additional partitions for special device mirror? Is this possible?

I have a small form factor system with only 2 m.2 slots. I've populated these with 2 micron 7450 Pro 1.92TB drives.

I would like to use these 2 nvme drives in a zfs mirror for the rpool, but I would like to reserve some amount of space, maybe 100GB on each drive to create a mirrored special device pool to attach to the spinning rust pool also on this system.

This is very easy on a non-boot drive but I can't figure out how do accomplish this in proxmox? It would be real easy if I could shrink the zfs partitions after installation but apparently that isn't possible?

Thanks for any help!
