Function ssm_ba_gates_hopper_enabled 

pub fn ssm_ba_gates_hopper_enabled() -> bool

Is the twin selected? — [defaults] ssm_ba_gates_hopper, with ATLAS_SSM_BA_GATES_HOPPER overriding (super::target_defaults).

No ATLAS_NO_* rung, unlike the GDN families: this lever has no accuracy question behind it, so there is nothing for a kill switch to outrank that ATLAS_SSM_BA_GATES_HOPPER=0 does not already say.
