PXE Boot menu architecture based

Question

Is it possible to hide/unhide PXE boot menu items? We have an x86 boot configuration for TinyCore. This works perfect with PXE boot. Now we want to add a Arm version of PiCore to the PXE menu so we can boot rPi's. For now we can only point to 1 default item in the PXE menu.

PXE menu:

 DEFAULT      vesamenu.c32
 PROMPT       0
 NOESCAPE     0
 ALLOWOPTIONS 0
 # Timeout in units of 1/10 s
 TIMEOUT 30
 MENU MARGIN 10
 MENU ROWS 16
 MENU TABMSGROW 21
 MENU TIMEOUTROW 26
 MENU COLOR BORDER  30;44   #20ffffff #00000000 none
 MENU COLOR SCROLLBAR   30;44   #20ffffff #00000000 none
 MENU COLOR TITLE   0   #ffffffff #00000000 none
 MENU COLOR SEL     30;47   #40000000 #20ffffff

APPEND quiet```

There is https://wiki.syslinux.org/wiki/index.php?title=Menu#MENU_HIDE

But I don't think there is anything that can change "on runtime"

With iPXE you could use a script that detects platform that adds relevant items, different beast and a bit longer startup stretch, but in the end opens up a bunch of possibilities. (iPXE can also be built for efi ARM)
