My Creality Ender 3 S1 Plus is a giant paperweight that can't even be used as a boat anchor, cause I'd be fined for polluting our waterways with electronic devices.
Not as dumb as yesterday, but stupider than tomorrow!
Most encoders of good quality should have the contacts open. At least I have not encountered any that was not.
But in case a contact on RB7,RB6 is closed I would definitely use a jumper. Not resistors.
