Yes, Equal-Cost Multi-Path (ECMP) for BGP routes is supported on NSF version 8.0.95 but it must be explicitly enabled and configured. From your screenshot the NSF has received two BGP paths for 172.20.10.0/24 (via 169.254.254.2 and 169.254.254.3) but only one path is installed in the routing table which confirms ECMP is not currently active.
