That is not the same use case. You are always including NetworkPkg/Network.fdf.inc and then inside of it you are using NETWORK_ENABLE flag to include the associated drivers or not include anything at all but the file exists. My use case differs where the file may not exist and that is why I have a conditional flag outside the include directive.

Try including unconditionally, and pushing down the !if into the includee.

This is known to work; see for example "NetworkPkg/Network.fdf.inc".

(The outermost "NETWORK_ENABLE" flag in "Network.fdf.inc" parallels your
use case.)
