As suggested by Mark, you can try ELRepo's kernel-ml or kernel-lt. In
both kernels, gadget is enabled in the config:

CONFIG_USB_GADGET=m

If you wish to build your own kernel, then try following the instructions in:

https://wiki.centos.org/HowTos/Custom_Kernel

Or you could build just a module instead of a whole kernel:
