BGP neighbor fall-over bfd without any extra options

Description
The option to set BGP neighbor fall-over bfd without any extra options seems to be missing.
The help during a configure terminal shows 5 scenarios: The default (<CR>) + 4 optional parameters:
awesome_router(config-router)#neighbor 192.168.1.4 fall-over bfd ?
check-control-plane-failure Retreive control plane dependent failure (c-bit) information from BFD for BGP GR/NSF operation
multi-hop Force BFD multi-hop to detect failure
single-hop Force BFD single-hop to detect failure
strict-mode Enable BFD strict-mode
<cr> <cr>
The provider documention specifies the 4 optional parameters:
- fall_over_bfd_check_control_plane_failure
- fall_over_bfd_multi_hop
- fall_over_bfd_single_hop
- fall_over_bfd_strict_mode
However, it does not seem possible to configure without the optional parameters.
Can you please tell us how to configure or implement this feature?
