contents	A search for Higgs boson (H) production in association with two vector bosons (V = W, Z) via vector boson scattering (VBS) is presented using proton-proton collision data collected at $\sqrt{s}$ = 13 TeV by the CMS experiment, corresponding to an integrated luminosity of 138 fb$^{-1}$. Events containing two forward jets consistent with VBS, a large-radius jet from the decay of a boosted H to a pair of b quarks, and 0, 1, or 2 charged leptons coming from V decays are selected. The process is excluded at 95% CL for observed (expected) values of the VVHH coupling modifier $κ_\mathrm{VV}$ outside the interval 0.40 $\lt$ $κ_\mathrm{VV}$ $\lt$ 1.60 (0.34 $\lt$ $κ_\mathrm{VV}$ $\lt$ 1.66), assuming standard model values for all other couplings, thus establishing a novel probe of the VVHH interaction. Constraints are also set on the individual $κ_\mathrm{2W}$ and $κ_\mathrm{2Z}$ coupling modifiers, and on the allowed region in the $κ_\mathrm{2W}$-$κ_\mathrm{2Z}$ plane.
