Based on the sales of The Switch, I highly doubt it. While I agree that it is due for a refresh, Nintendo doesn't really chase high end graphics. They'll put out new hardware eventually that is more powerful than the current Switch, but less powerful than a PS5. They have a bunch of IPs that they know will carry it regardless of if it's cutting edge or not.
