Could just include an option in the settings to allow the player to enter their own dice values (or perhaps select succeed or fail) in whichever situations bring the dice up on screen. That way if people want to roll their own irl dice they can, or if they want to ‘cheat’ to avoid savescumming past checks they can. If it means disabling achievements or whatever, who cares.
I personally wouldn’t use it, at least not on first playthrough, but I don’t see who it would hurt to include that option. There will be difficulty settings which make combat trivially easy, so I don’t really see the difference with an option which bypasses the RNG element of checks, if the player wants to use it.
