How to define my dns servers in resolv

[znavko]

Hello! I cannot agree limitations my provider setup
with the orders of Russian government to forbid access
to this or that website, for example,
protonmail.com, tutanota.com, vpnbook.com are prohibited.
Does any civilized country do such a harm?

I wish to use my own DNS servers from free and secure services.
I want to start just to type them into /etc/resolv.conf

And may be further actions will be dnsmasq with wpa_supplicant
with your help.

Can I deal with resolv.conf without dnsmasq?

Can you advise me manual page or example where resolv.conf is
configured?? I did not find it except notes in dnsmasq configurations.
