I suggest you take a look at some of the USB examples, for instance this one combine HID and CDC:
https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/zephyr/samples/subsys/usb/hid-cdc/README.html

As a USB device there is nothing you need to do, it is the USB host that handle timing.

Yes, it will conflict.

But USB spec has a method to resolve the conflict: IAD (interface association descriptor). That is how you can combine CDC with Mass storage or HID in a single USB device.
