Thanks to multiple mentions of Mullvad in this overall post comments, I decided to replace dnsmasq with unbound and convert the laptop to DoT. Here's the specific Mullvad snippet if anyone needs:

    # Mullvad Unfiltered
      forward-addr: 2a07:e340::2@853#dns.mullvad.net
      forward-addr: 194.242.2.2@853#dns.mullvad.net
    # Mullvad Adblock
    #  forward-addr: 2a07:e340::3@853#adblock.dns.mullvad.net
    #  forward-addr: 194.242.2.3@853#adblock.dns.mullvad.net

As mentioned in the default unbound config, the "#" is not a comment when used in the value, it's used for TLS checks. I followed this simple blog post from years ago: https://www.jwillikers.com/dns-over-tls-with-unbound
