How do you set OPNsense to use a different DNS than your ISP's?

Sometimes what should be the simplest questions are the hardest ones to find an answer to.  I just want to set it so that when OPNsense goes out to get updates, etc. it uses Google's DNS rather than my ISP's, because my ISP's DNS is horribly slow.  I am hoping that you do not have to make changes in Unbound, because it seems that when people do that they then have all kinds of DNS issues.

I found these settings, if I just enter the DNS I want to use in those fields will that be sufficient, or is that for some other purpose entirely?

I'm a home user of OPNsense, not a networking expert.  I'd much appreciate it if you'd keep that in mind if replying to something I posted.  Many thanks!

If you want to change DNS setting system wide then look under System ==> Settings ==> General, there is a section for DNS servers and option to disallow overwriting by DHCP on the WAN side.

HTH.
