Force INIT section to not be RWX and become RX to pass HLK?

My NDIS is failing at HLK Hyper-V readiness, because of the following error:

Non-zero Code Integrity statistic found: Execute-Write Section Count: == 1

Checked the .sys file, turns out the INIT section is RWX.

We are not changing the attribute of the INIT anywhere so this seems to be the default, we are only using #pragma NDIS_INIT_FUNCTION(DriverEntry).

Tried adding

LINKERFLAGS = $(LINKER_FLAGS) /SECTION,INIT,RX

To the sources file, no luck, Tried adding

#pragma comment(linker, "/section:INIT,RX")

To the source code, still no luck. We are building it using DDK 7600.

How can i force the INIT section to not be RWX?

    Why are you using such an old DDK? Seems like you will run into multiple problems trying to get that build environment to produce binaries compatible with the latest generations of HLK tests. When I build a driver with the latest WDK, also not changing any attributes, dumpbin /section:INIT reports "Execute Read"

    And why bother using an INIT section at all? That made sense back 20 years ago… today, with big memory machines, not such a big deal.
