You need your CARP-redounding interfaces to be in a port group that has promiscuous mode, MAC address changes, and forged transmits enabled. I've seen this best documented by the other sense, at https://docs.netgate.com/pfsense/en/latest/troubleshooting/high-availability-virtual.html?highlight=vmware#hypervisor-users-especially-vmware-esx-esxi; but there are also blog articles you can find if you search for "carp vmware" or so.
If you have multiple physical uplinks for the vswitches in your VMware servers, see the above and also https://kb.vmware.com/s/article/59235, on the /Net/ReversePathFwdCheckPromisc setting.
