Yes. I also tested with the following diff applied instead of the module
parameter:

----------8<----------
diff --git a/drivers/acpi/x86/s2idle.c b/drivers/acpi/x86/s2idle.c
index 6a2c94fdbeae..a247560e31de 100644

The full DMI Product Name is "ROG Zephyrus G14 GA402RJ_GA402RJ", but
there is also a near-identical higher spec model GA402RK.
