  We investigate the effects of $p$-wave interactions on Efimov trimers in
systems comprising two identical heavy fermions and a light particle, with mass
ratios larger than $13.6$. Our focus lies on the borromean regime where the
ground-state trimer exists in the absence of dimers. Using pair-wise
Lennard-Jones potentials and concentrating on the $L^{\pi} = 1^{-}$ symmetry,
we explore the critical value of the interspecies $s$-wave scattering length
$a_{c}$ at which the borromean state appears in several two-component particle
systems. We study the universal properties of $a_{c}$ and the influence of
$p$-wave fermion-fermion interactions on its value. Our findings show that, in
the absence of $p$-wave fermion-fermion interactions, $a_{c}$ is universally
determined by the van der Waals radius and mass ratio. However, when attractive
interactions between the two fermions are introduced, the formation of the
borromean state becomes favored over the absence of $p$-wave fermion-fermion
interaction. Furthermore, we demonstrate that the $p$-wave Efimov effects
persist even when the fermion-fermion interaction is taken to the $p$-wave
unitary limit.
