We show that this process is sensitive to significant deviations of Higgs couplings to first- and second-generation SM quarks (particularly the up type) from their SM values, and we use a multivariate neural network analysis to derive the prospects of the High Luminosity LHC to probe deviations in the up and charm Higgs Yukawa couplings through h+γ production. ; Horizon 2020 Framework Programme 860881,SEV-2016-0597 H2020 ; Ministerio de Ciencia, Innovación y Universidades MCIU ; European Social Fund PGC2018-096646-A-I00,PRE2018-083563,RYC-2017-22986 ESF ; Agencia Estatal de Investigación PID2019–110058GB-C21 AEI
