Neutrinos with energies ranging from GeV to sub-TeV are expected to beproduced in Gamma-Ray Bursts (GRBs) as a result of the dissipation of the jetkinetic energy through nuclear collisions occurring around or below thephotosphere, where the jet is still optically thick to high-energy radiation.So far, the neutrino emission from the inelastic collisional model in GRBs hasbeen poorly investigated from the experimental point of view. In the presentwork, we discuss prospects for identifying neutrinos produced in suchcollisionally heated GRBs with the large volume neutrino telescopes KM3NeT andIceCube, including their low-energy extensions, KM3NeT/ORCA and DeepCore,respectively. To this aim, we evaluate the detection sensitivity for neutrinosfrom both individual and stacked GRBs, exploring bulk Lorentz factor valuesranging from 100 to 600. As a result of our analysis, individual searchesappear feasible only for extreme sources, characterized by gamma-ray fluencevalues at the level of F$_{\gamma} \geq 10^{-2}$ erg cm$^{-2}$. In turn, it ispossible to detect a significant flux of neutrinos from a stacking sample of ~900 long GRBs (that could be detected by current gamma-ray satellites in aboutfive years) already with DeepCore and KM3NeT/ORCA. The detection sensitivityincreases with the inclusion of data from the high-energy telescopes, IceCubeand KM3NeT/ARCA, respectively.
