Yeah, depending on the string to be plucked, you can mute using either left hand or right hand fingers. Have also learnt muting using right palm/thumb like guitarists across strings in some situation - for example play solo notes on G string.
One simple way to mute strings without special technique is to use a hair scrunchy/band. Get a cheap one, or 'borrow' from wife/GF. I do that if I want to try tapping.
