At the end I've set max_workers parameter to 1 (basically revert it to PVE 6 default) and the backups didn't cause issues to the guest VMs (or at least there were no notifications, and the checks I made were all negative). Next week, when the upgrade is finished, I will try "fleecing" and I will revert the max_workers configuration to the default values to see validate the setup. Also, in the short term, I'm planning to change the target storage for vzdump to something more fast. Have a great day!
