Put your cameras on a VLAN and block their internet access with firewall rules. You can let them resolve DNS and they will usually quiet down a bit.

There is 0 chance my wifi reaches to my back 40, so I have to use cellular data. So I need the camera to encrypt the data before sending.
I mean its probably not cost effective to protect the privacy of your critters, but Unifi makes some incredible network extension gear:

Ethernet limit is about 100m. so maybe you could also just run a cable and put up a POE access point ..
This is good advice.
Still interested in other answers though. Can you purchase cameras for your property where the CCP isn't watching you like you're in the Truman Show? I mean, do they exist?
