How do I lower my ELO/MMR in norms?

Hi pretty much title.

I am constantly matched with high plats, diamonds and low masters. This is extremely annoying because 9 times out of 10, they are sweaty and tryhard. I come back from late night shift and I want to have a chill bronze or silver or even iron like game. I don't want to have to deal with a sweaty 9 cs a minute yasuo stutter stepping who is otp master. I don't want to have to sweat. I just want to chill and have a chill league game where it is fun. It is to the point where I am considering making another acc just to play bronze. It is not to say that I don't sometimes enjoy the challenge because I was low diamond ranked, but that was ages ago. I want to play league for fun not league to stress. Do I have to run it down to drop this and match with silvers/bronzes?
