Context?
What Operating System is running on your RPi4 board?
In what application, tool, utility or programming language do you want to make this change?

You can't - or at least, not easily.
If a serial device identifies as a Abstract Control Model (ACM) device, the kernel has assigned the name before you can do anything with it. There might be a udev rule you can apply, possibly, to fix the name.
Do you have an application that will only work with /dev/ttyUSB* devices? Because /dev/ttyACM* should behave the same way.

With so little information, the only possible answer has to be something vague like "change that string in the script you are using."
