To elaborate on what the others are saying the only way to jailbreak the Switch V2 or a Switch lite is to use a hardware modification called a SX Core (or SX Lite if you have a lite). These are difficult to install without the proper equipment though so you should play someone to do it. The chip itself costs about £50 and I've seen installation services between £30 and £60.
@squee666 installed mine for me, I think he charges £50 if I remember correctly. Squee doesn't sell chips though so if you ask him to install it you'll have to buy one and ship it with your Switch to him. It's against the rules to link to SX products here but they're easy to find on google.
If you join the Team-Xecuter support chat you can find a list of installers and the region they're in but I'm going to shill Squee because he's in Ireland so shipping shouldn't cost you much plus we've spoke a bit and he's been very kind to me despite us not knowing each other very well.
