It's possible to modify RPG Maker to create the TRPG you want, but the problem is that modifying it requires a certain level of proficiency with the tool. If you use someone else's plugin (for example, I found one here: https://himeworks.itch.io/grid-battle-system), you'll be limited to what that plugin allows unless you know how to modify it.
If you search, you'll likely find templates for Unity and Godot. I found this one for Godot 4:

Exactly which path is easier depends on you and your prior knowledge. Personally, I would spend a few days with each option to see which one are more comfortable or which one as having more potential.
