2G preferred network type on Android 13

I'm using a crDroid rom on a Samsung S8 phone and I have realized that google decided to fight 2G networks. I have only 3G and 4G options for preferred network type now in the rom settings. And if I use a method that worked beautifully on android pie, it no longer works on android 13. When I set the type to 2G, the network type doesn't change and the rom settings displays something like "invalid value, defaulting to 4G". But I found out I can still change it by using the phone app, inputting *#*#4636#*#* and then selecting 2G. This way 2G is even displayed in the rom settings and it works. But as soon as I change it to 4G, the only way to get back to 2G is to input the code again in the phone app. I would like to have some automation to switch between 2G and 4G. Preferrably with a quick settings tile. So, is there a way to achieve this in a more effective way?
