Also unrelated to Genshin, but always check if a game has private servers (generally a google search of game x private server github) will point you in the right direction. Whether or not to host your own vs. playing on someone else's instance is something you have to decide for yourself, but with the hyper-monetization of games it's almost always worth checking if you/a good person with a server is pushing back against the monetization schemes.
