Go to your NextDNS Settings page and look for the Rewrites section towards the bottom.  It will let you redirect one site to a different IP or other FQDN.  Note that this is a simple DNS hostname redirect only.  There's no way to make a query on Bing automatically parse on Google via a DNS query using a DNS service like NextDNS.

rewrites can do this. Or you can use a metasearch engine, and set up the customization to not use search engines you want, then save the settings and have each student device use those settings.
