How to use crynchyroll safely ?

I have my modded oled for over a year now, I never used semi-stock and sysnand, someone (chatgpt) told me I can use crynchyroll on semi-stock mode but as soon as I boot into it , all the sideloaded games started updating I turned on the aeroplane mode and then switched back to emunand, today again I asked chatgpt and now it's saying I should use sys-nand , and don't touch semi-nand Now I'm so confused , please help me which one should I used also does my switch is on the risk of getting ban because of what happened
