DNS over TLS

[nbctcp]

As I know there are few DNS server support TLS. As shown below   ===== DNS over TLS Cloudflare cloudflare-dns.com (1.1.1.1:853) cloudflare-dns.com (1.0.0.1:853) cloudflare-dns.com ([2606:4700:4700::1111]:853) cloudflare-dns.com ([2606:4700:4700::1001]:853) Google dns.google (8.8.8.8:853) dns.google (8.8.4.4:853) dns.google ([2001:4860:4860::8888]:853) dns.google ([2001:4860:4860::8844]:853) Quad9 dns.quad9.net (9.9.9.9:853) dns.quad9.net ([2620:fe::fe]:853)   In order to enable DNS over TLS, I think I need to use those dns servers   QUESTIONS: 1. I want to enable "DNS over TLS" and Internal DNS as well to solve internal server name I think if I can't use "DNS over TLS" if I point to Internal DNS Can I use split DNS like this  config system dns-database edit "company1.com" set domain "company1.com" set authoritative disable set forwarder "10.243.13.1" next end

2. can I enable that using this command

config system dns
    set primary 8.8.8.8
    set dns-over-tls enforce

set ssl-certificate Fortinet_Factory

end 

  tq

UPDATE1: 1. I think this is the answer https://www.youtube.com/watch?v=3Ze3jMAdRTo&feature=emb_logo I need to setup dns server in Fortigate interface facing LAN/DMZ
