In short no, but;
If you google up "Halflife 2 build 2153" or "2187" you'll find versions were people have switched the SecuROM hl2.exe with the .exe from the modern DRM free steam release.
It's older versions like these that speedrunners use as they contain the old exploits for speeeed!
(plus they work on Win98SE for me without the need for anything like KernelEx.)
