  In this paper, based on the notion of Gauge/Gravity duality, we explore the
laws of entanglement thermodynamics for most generic classes of Quantum Field
Theories with hyperscaling violation. In our analysis, we note that for Quantum
Field Theories with compressible \textit{quark} like excitation, the first law
of entanglement thermodynamics gets modified due to the presence of an
additional term that could be identified as the entanglement chemical potential
associated with \textit{hidden} Fermi surfaces of the boundary theory. Most
notably, we find that the so called entanglement chemical potential does not
depend on the size of the entangling region and is purely determined by the
quark d.o.f. encoded within the entangling region.
