It's not made very clear from the documentation. I assume there are good
technical reasons why the cluster traffic would be impacted.
Afaik, proxmox leverages corosync which can leverage multicast for the
cluster checks. I don't think it can be badly impacted by LACP but
something to keep in mind.
There is this old thread with a similar discussion :
