No, unless it’s were a cli image viewer. The gui parts of the OS, and what’s written by Apple, use keychain.

Macs have two completely independent root CA stores. The cli and all the opensource parts use /etc/.

Curl project did actually release support to compile it with default keychain support a year ago, but of course Apple never updates their cli tools, so expect to see that in macOS 37.

Note: I’m not defending Apple here.
