When using bridge neighbor suppression in EVPN deployments, Duplicate
Address Detection (DAD) is currently broken for both IPv4 (ARP probes)
and IPv6 (DAD Neighbor Solicitations). This prevents proper address
conflict detection across the VXLAN fabric.
The neighbor suppression feature allows the bridge to reply to ARP/NS
messages on behalf of remote hosts when FDB and neighbor entries exist,
suppressing unnecessary flooding over the VXLAN overlay. However, the
current implementation unconditionally suppresses ARP probes and DAD NS,
which breaks DAD.
[...]
Here is the summary with links:

You are awesome, thank you!
