  We investigate the dynamics of fermion localization within the framework of
$f(T, B)$ gravity featuring non-minimal couplings. Starting from the Dirac
action for a spin-$1/2$ fermion in a five-dimensional spacetime governed by
torsional $f(T, B)$ gravity, we derive the Dirac equation and we explore its
solutions under various non-minimal coupling functions. We examine two
realistic forms of the torsional non-minimal coupling and reveal distinct
behaviors that impact the localization of both massless and massive fermionic
modes on the brane. Additionally, we employ probabilistic measurements,
including Shannon entropy theory, Fisher information theory, and relative
probability, to analyze the localization of these fermionic modes. The observed
effects offer potential insights into probing torsional modifications.
