bfd is able to monitoring static routes , using profiles and multi-hop to reached a peer :

vyos@rt-1# run show configuration commands | match static
set protocols bfd profile static interval multiplier '3'
set protocols bfd profile static interval receive '300'
set protocols bfd profile static interval transmit '300'
set protocols bfd profile static_m interval multiplier '5'
set protocols bfd profile static_m interval receive '800'
set protocols bfd profile static_m interval transmit '800'

set protocols static route 10.10.13.3/32 next-hop 192.168.2.3 bfd profile 'static'
set protocols static route 172.16.10.3/32 next-hop 192.168.10.1 bfd multi-hop source 192.168.2.1 profile 'static_m'
set protocols static route 192.168.10.0/24 next-hop 192.168.2.3

operational commands :

vyos@rt-1# run show bfd static routes
