Redirect printf and Console to custom function

Can I redirect/reroute printf functions and also all console messages to my own written functions? What exactly I need is to route them to my own software uart that I have written by myself. Why? 3 HW UARTS are very busy already doing their job and we need one more SW UART for getting messages from the processor.

Already done. I have found different solutions but not redirecting to SW UART or my own custom function.

But does anybody know how to exactly redirect printf to my own function?

quite some information provided here, but..
this is not for the real printf, which goes over vfs console file descriptors
this is all is for the ESP_LOGx facility..
hence again, the question:
is there an easy way to override the destination for printf (whatever is defined in sdkconfig) to, say, log in a buffer ?
I mean without messing with the vfs or trying to redirect or sth like that..
Any help is appreciated
