During the last years the analysis techniques to measure the Higgs boson coupling to charm quarks using the full Run-2 data of the CMS experiment have been established. The Higgs boson decay into charm- anticharm pair, where the Higgs boson is produced in association with the W or Z boson, has been analysed in a resolved topology with individually reconstructed jets and in a boosted topology with merged jets. In this talk a concept of a new analysis framework is presented with the intention to reproduce the known results of the VH search from Run-2 analysis by CMS. The Z → 2l decay channel of the associate vector boson and resolved jet topology of the H → cc decay are considered for this study. Furthermore, the results of the current state of ML-supported analysis in the new framework will be discussed.
