How to remove a snake from a tiny hole in the generator?

I’ve browsed through just about all the snake related questions on this sub and haven’t seen this one yet. So here goes.

Yesterday, I found a black rat snake (almost certain, but given one of the answers on here, I am probably misidentifying the snake) about 4 feet long in my backyard. I’m in Charlotte, NC, where black rat snakes are very common. I saw this snake casually slither across my yard, crawl all the way to the other side, and casually enter a teeny hole in the underside of my outdoor generator unit. The confidence and familiarity with which this lil guy crawled in there makes it seem like there’s a nest down there. I’ve already seen a lil baby snake a few weeks back, so I’m confident on the nest part.

My question is a two part question:

1. I understand that black rat snakes, if it is indeed one, are non-venomous. But a 4 foot long snake surely gives me the creeps. Also, I’ve been thinking about selling my generator (recently bought the house and it came with it, but I have no use for it since we hardly lose power and it runs on gas and that gives me anxiety). If I were to call someone (there are several online folks that just come pick up your generator and pay you for it), they’d absolutely refuse to take the generator if there’s a snake nest on under it. I don’t want to trick them into doing it anyway, that’s just a lawsuit waiting to happen. I highly doubt that a pest control company would have the skills required to be able to remove the generator to clear out the snakes. So my question is, how do I get this snake, and any possible babies out of this lil hole? The best answer would be I can do this without pulling the generator out to reveal a hundred snakes waiting to strike.
2. I had the chance yesterday and I might have it again, but if I do, what do I do if I were to try to catch it? I can take all proper precautions and capture it. Then what? I live in the city. The road outside my front door has a speed limit of 35 but an average vehicle speed of 50 MPH and is a Heavy traffic area. I cannot release it in the front. The back is another house and not the woods. There aren’t any proper fences that can keep the snake away and I am positive it is bound to come back to its nest if I tried. So If and when I catch this snake, where do I put it after?

I don’t care if this snake helps with the rodents and is non-venomous, I don’t want a 4-foot snake in my yard. I’d like to not kill it, but I definitely need to do something with it that makes me feel like it does not exist in my life anymore. I hope I’m not coming off as hateful, I just really don’t like snakes.

Thank you
