Static IP from ISP

I am behind a CGNAT. Currently the ISP provided router does not let me edit DNS in the WAN page. Although it allows changing DNS on LAN/DHCP page.

So I am thinking of buying a static IP from my ISP as this would solve the port forwarding issues I have running plex, xbox, CCTV etc

But with static IP comes security issues. Although I have a TPLink Deco X60 which is connected to the ISP provided router I think there is still a security risk. 

So my question 

1 - Having a NextDNS solution help me with a good firewall or save my network in some way.

2 - As the ISP does not allow editing the WAN page, will NextDNS still work after I change the DNS to NextDNS provided DNS in LAN/DHCP.

The idea is that whoever connect to the TPLink Deco X60 router goes through NextDNS provided DNS.

 

(I was a very old NextDNS user - 2020 and then stopped using in 2023)

    1) Possibly but only for outgoing connections, i.e. blocking malware domains. 
    2) Yes, it will still work and is the more preferred location to set DNS on the router. Don’t forget to link the IP or it won’t pick up your profile configuration. (CGNAT won’t link correctly so it definitely won’t work)
