The search for the Higgs boson decay into a charm-anticharm pair in events where the Higgs boson is produced in association with a W or Z boson is an important contribution to the aim of measuring the Higgs boson coupling to charm quarks. In addition to the so-called "resolved" event topology, the topology with highly energetic Higgs boson decays, resulting in a boosted event topology is explored. The potential improvement on the analysis sensitivity when adding the boosted topology is investigated. This talk presents the first expected results using early Run-3 data recorded by the CMS experiment focusing on the preliminary expected limits on the Higgs-charm coupling.
