Can I using GPIO4 for input in WP7605

Can I using GPIO4 for input in WP7605?

I got error message when I export GPIO4 as input pin :
root@swi-mdm9x28-wp:~# echo 4 > /sys/class/gpio/export
sh: write error: Operation not permitted

and I check the gpio configure with AT command :
AT+WIOCFG?4
+WIOCFG: 4,3,0,0,1,0,0

it seems set to sim detect pin

It seems that the setting of this pin cannot be changed

I don’t see problem in WP76 FW R13.3:
