Is it even possible on android? Is there a FOSS dialer to optionally encrypt some phone calls (non voip) using a pre-shared key with other party?

With audio encryption hardware, sure. Speak into that and feed its output to the mic on the phone
I think they are interested in a purely software solution
I think you’re right. I know for a fact that I do not know of any, not for regular phone calls. Obviously if you want to use the internet and data, there’s tons of options.

I don’t myself. So I am not sure.
