First of all, a huge thank you to @Gristle for this solution
The first thing to do is, create a new PSC (I recommend Notepad++ as editor)
Open Notepad++\New and insert this compilation
Scriptname MYMOD_Access_SLSF Hidden
SLSF_CompatibilityScript Function GetSLSFAPI() Global
Return Game.GetFormFromFile(0x0001E157, "SexLab - Sexual Fame [SLSF].esm") As SLSF_CompatibilityScript
EndFunction
Bool Function IsSLSFLoaded() Global
