How to use custom menus with netbootxyz running on a TFTP server on OPNSense

[Darkfella]

I decided to run netbootxyz directly on OPNSense but i have some issues with figuring out how to use custom menus which are saved on my tftp's server instead of netbootxyz using the ones hosted on github. I created boot.cfg and windows.ipxe files inside /usr/local/tftp but when network booting its using the default ones and not the ones i modified locally on my machine. Do you guys have any tips to help me out
