add this to /boot/grub/grub.cfg, this works for me:

menuentry "iPXE Netboot.xyz" {
    insmod chain
    set root=(hd0,1)
    chainloader /iso/ipxe.efi
    boot
}

@Kipjr Thank you for spending time and trying to help.

I was trying to load grubnetx64 (2.04, from ubuntu 20.04) over network, and then chainloader to netboot.xyz downloading over internet, without success.

But I made an exercise using the grubnetx64 from github (2.11) generated by myself and ipxe from github (1.21) and it was possible to load ipxe capable to use the internet. So I think the grub 2.04 is the culprit.
