asus_atk0110 uses ACPI to talk to the device, and thus it checks for
acpi_enforce_resources=strict and assumes that if you set
acpi_enforce_resources=lax that you don't want to use
this ACPI driver and are instead using a different native driver:

hwmon: (asus_atk0110) Don't load if ACPI resources aren't enforced
When the user passes the kernel parameter acpi_enforce_resources=lax,
the ACPI resources are no longer protected, so a native driver can
make use of them. In that case, we do not want the asus_atk0110 to be
loaded. Unfortunately, this driver loads automatically due to its
MODULE_DEVICE_TABLE, so the user ends up with two drivers loaded for
the same device - this is bad.
So I suggest that we prevent the asus_atk0110 driver from loading if
acpi_enforce_resources=lax.

So you have to decide how you are going to access the hardware
on this machine. The default assumes that you are using ACPI
and that it is not safe for native drivers to simultaneously
touch the same HW that ACPI touches.
If you disable that check, then you will add risk of conflicts
to your system, and the asus_atk0110 driver will refuse to
operate under such conditions.
