Override/disable DNSSEC system?

I do. I have a full list of them. That is not the issue. The attached screenshot captures the very situation I deal with regularly throughout the day. If I use the direct connection to my internet modem, it still works. Through IPFire, I get this and it can take a long time for it to recover. Very frustrating. I have years of using IPFire behind me and have my network set up to use it for managing user access, Update Accelerator, etc., etc. So I’m invested in IPFire, but this problem with Unbound is incredibly frustrating.
