Depends on a lot of factors...
Proxmox isn't offering this as a feature, so you would need to use some workarounds like directly backing up the virtual disk on the underlaying storage instead of the VM itself. Or to not backup the whole disk but to do the backups on the guest's filesystem level.

I really wish this was an option. It would be ideal if we could select which disks to backup from a VM. My backup location is limited and I have additional drives on VMs that are outright unimportant that are both increasing my backup times and the used backup space.
you can configure which disks/volumes to include in backups (right on the disk/mountpoint itself there is a "backup" flag). you just can't set that on the backup job level - that would make it very confusing afterwards since the contents of backup archives would change depending on which job created them.
