  Here, we explore the formation of primordial black holes (PBHs) within a
scalar field inflationary model coupled to the Gauss-Bonnet (GB) term,
incorporating low-scale spontaneously broken supersymmetric (SB SUSY)
potential. The coupling function amplifies the curvature perturbations,
consequently leading to the formation of PBHs and the production of detectable
secondary gravitational waves (GWs). Through the adjustment of model
parameters, the inflaton can be decelerated during the ultra-slow-roll (USR)
phase, thereby augmenting curvature perturbations. Swampland criteria are also
investigated. Our computations forecast the formation of PBHs with masses on
the order of ${\cal O}(10)M_{\odot}$, aligning with observational data from
LIGO-Virgo and PBHs with masses ${\cal O}(10^{-6})M_{\odot}$, offering
potential explanation for ultrashort-timescale microlensing events recorded in
OGLE data. Additionally, our proposed mechanism can generate PBHs with masses
around ${\cal O}(10^{-13})M_{\odot}$, constituting roughly 99$\%$ of the dark
matter. The density parameter of produced GWs ($\Omega_{\rm GW_0}$) intersects
with the sensitivity curves of GW detectors. Two cases of our model fall within
the nano-Hz regime. One of these satisfies the $\Omega_{\rm{GW}}(f) \sim
f^{5-\gamma}$ fit, with the derived $\gamma = 3.51$ matching the NANOGrav
15-year data.
