We investigate the sensitivity of the upcoming high luminosity run of the LHC to di-Higgs production and subsequent decay to dark matter in the context of the singlet scalar extension of the SM augmented by a fermionic dark matter in the dark and bright channel <math><mrow><mi>\u03b3</mi><mi>\u03b3</mi><mo>+</mo><msub><mrow><mrow><mi>E</mi></mrow></mrow><mrow><mi>T</mi></mrow></msub></mrow></math>.

We further show that in a multivariate analysis, for an invisible branching fraction as low as <math><mo>\u223c</mo><mn>10</mn><mo>%</mo></math>, we obtain stronger bounds for the Higgs trilinear coupling from the <math><mi>\u03b3</mi><mi>\u03b3</mi><mo>+</mo><msub><mi>E</mi><mi>T</mi></msub></math> channel compared to the <math><mi>b</mi><mover><mi>b</mi><mo>\u00af</mo></mover><mi>\u03b3</mi><mi>\u03b3</mi></math> final state.
