[syslinux] syslinux.efi does not seem to support HTTP like lpxelinux.0 does?

Hello everybody,
I been add this for a while and sent an message last year as well, but
still have the issue.
I am using syslinux-efi from debian version
3:6.04~git20190206.bf6db5b4+dfsg1-1
# md5sum /usr/lib/SYSLINUX.EFI/efi64/syslinux.efi
7ccde7e6ca2756931d6a4ebd8b55a753 /usr/lib/SYSLINUX.EFI/efi64/syslinux.ef
# md5sum /srv/tftp/efi64/syslinux.efi
7ccde7e6ca2756931d6a4ebd8b55a753 /srv/tftp/efi64/syslinux.efi
Apr 26 18:54:58 firewall01 dnsmasq-tftp[23829]: sent
/srv/tftp/efi64/syslinux.efi to 192.168.40.112
With efi64 syslinux.efi KERNEL
http://192.168.40.25/linux-iso/image/vmlinuz will not load while
/usr/lib/PXELINUX/lpxelinux.0 works fine with BIOS boot, but I need EFI
for TPM support.
Would it be possible to add HTTP support to the EFI syslinux images.
I rather not build my own ipxelinux.0
Kind regards,

> ipxelinux.0 is ipxe with syslinux embedded (https://coderwall.com/p/0sq9gg/how-to-build-ipxelinux-0). If you want an EFI version, you will probably have to build one yourself. I've done similar things (https://fedoramagazine.org/how-to-build-a-netboot-server-part-3/#:~:text=First,%20update%20the%20init.ipxe%20script), but it is too complicated to explain in an email.
