DoH does not prevent your ISP from seeing the IP addresses of the websites you visit. It only encrypts the requested url. It is not too difficult to figure out which IP addresses are from which websites and block or manipulate them.
Learned first hand when trying to visit adguard.com with DoH enabled at a relative's. Comcast's router blocked the website by recognizing adguard's unencrypted website IP address.
DoH is not really hiding anything from ISP's.
