Suppress CoreGraphics or Image I/O Console Messages

I'm using CoreGraphics and Image I/O in a MacOS command-line tool. My program works fine, but after the first drawing to a bitmap context there are messages output to the console like the following:

2022-12-20 16:33:47.824937-0500 RandomImageGenerator[4436:90170] Metal API Validation Enabled
AVEBridge Info: AVEEncoder_CreateInstance: Received CreateInstance (from VT)

AVE ERROR: XPC failed
AVEBridge Info: stopUserClient: IOServiceClose was successful.

AVEBridge Error: AVEEncoder_CreateInstance: returning err = -12908

These messages get in the way of my own console output. How do I stop these messages from being displayed?
