user24327: Are there any possible moves to checkmate a Black opponent if we have a White bishop and king?

user-1: It is impossible. The Black king cannot be checkmated. In the case that the Black king goes into the 'right' corner, then it may be checked by the bishop. However, it must have at least 1 escape square. In the wrong corner, then Black cannot be checkmated no matter what.

user24174: There is no way to force a win with KB vs K.
No way for them to blunder into it.
No way for them to help you selfmate.

user4418: No. There is no position you can construct in which the black king is in check (has to be from the bishop), white only has king and bishop and the black king can't move.
The closest you can get is this:
[fen "k7/1BK5/8/8/8/8/8/8 w - - 0 1"]

And the black king can move to a7.
