dracut/initramfs only needs to be updated if the hardware is needed for boot pre-pivot root (ie to find rootfs, or if you use root on nfs then you need network in initrd).
If in your m.2 case you were booting from it then extra drivers would need to be loaded such that the initramfs can find rootfs. Any pci cards and/or usb devices when the device is seen something will check the modules.dep file and look whatever module claims to support it. Usb devices load in a similar way.
