You could use DoH, which you should do anyway. No reason to leak DNS lookups to anyone.

DoH alone is not enough due to https://en.wikipedia.org/wiki/Server_Name_Indication being sent in plain text. Some day ECH (formerly, eSNI) should help with that.

I thought TLSv1.3 already encrypted the SNI?

No. ESNI is an later-created extension to TLS 1.3

It does

ESNI is not implemented yet on any website. And there is no software support except beta versions of Chrome/Edge and you have to manually toggle flags in dev mode.

All SNIs are passed as plain text to your ISP/VPN, even with DoH/TLS secure DNS enabled.

you'll always be leaking it to whoever you are sending your query to.
