Lenovo 300e Read & Write Protection, Still Enabled?

Hello, so recently I’ve delved into disabling Enterprise Enrollment on my Lenovo 300e Chromebook (Model Name: 81H0) and I understood taking the battery out should solve this, but removing the Read / Write Protection Functionality. However, after booting into Developer Mode I’ve noticed it still is blocked my enterprise enrollment. I tried removing a screw that seemed obviously out of place, but to my avail, no luck. Could anyone help me out? Thanks.
