An interaction at the tree level is a common feature of new physics models that feature scalar triplets. In this study, we aim to probe the strength of the aforementioned interaction in a model-agnostic fashion at the futuristic 27 TeV proton-proton collider. We assume that the 
couples dominantly to (
) and (t, b) and specifically study the processes that involve the vertex at the production level, that is, 
and 
. Moreover, we look into both 
decays for either production process. Our investigations reveal that the 
production process has a greater reach compared to 
. Moreover, the discovery potential of a charged Higgs improves markedly with respect to the earlier studies corresponding to lower centre-of-mass energies. Finally, we recast our results in the context of the popular Georgi–Machacek model.
