These kind of filters are usually third party software that is complete garbage. We had one in my high school, which could be bypassed just by going to the target URL, it will get blocked and then you would submit feedback as an incorrect block. Would let you through every time. I don't think they would go through those lengths to block DNS requests to certain names. And if you really wanted, you could set a DNS server to Cloudflare's 1.1.1.1, or Google's 8.8.8.8 for a while, let it resolve the DoH server name and use it like that. At that point, they need packet inspection firewall, which is an almost forgotten hardware now.
