I would say that the better option is to use bootnetx64.efi - that is
a copy of shim, which should then load grubx64.efi and its config and
go from there. For local testing my DHCP server has the following
snippet:
host sledge {
hardware ethernet d0:50:99:60:3b:fb;
fixed-address sledge.einval.org;
next-server 10.13.0.1;
if option arch = 00:07 {
filename "debian-installer/amd64/bootnetx64.efi";
} else {
filename "pxelinux.0";
}
}
where debian-installer is a copy of Buster's netboot files on the tftp
server. That works fine for me. If you're having problems, check that
the client is attempting to download the correct files from the TFTP
server. That's the most common problem in my experience, and Debian
used to have a problem here when we added SB support until I fixed it.

Not at all, no. The default grub config should work just fine.
