I don't know how to disable cache, but the changes you make are visible to customers in a maximum of 1 day. that cache doesn't bother you at all. I had the same problem. But if you want to see your site urgently, you can use:

https://yourdomain.com/?what-ever-you-want

After '?' you can set anything you want, but you have to change every time, because it acts as a variable and stores the current cache, setting aside the previous one. For visitors the changes will definitely be made. Do not worry.
