Issues with Enabling Explicit Proxy and Advanced DLP Features on Fortigate 60F

Dear Fortinet Support Team,

I am currently facing two issues with my Fortigate 60F device, running firmware version 7.6.1, and I would appreciate your assistance.

1- Enabling Explicit Proxy:
I am trying to enable the Explicit Proxy feature on my Fortigate 60F device. However, I am unable to find this option in the "Feature Visibility" section. Could you please guide me on how to enable this feature or help me identify why it's not appearing in the list?

2- Advanced DLP Features:
The "Advanced DLP Features" are currently disabled, and I received the following message:

To use the advanced features, the main Data Loss Prevention feature must first be enabled in Feature Visibility or via the CLI:  config system settings   set gui-dlp-profile enable end

Unfortunately, I received the following error message:

command parse error before 'gui-dlp-profile' Command fail. Return code -61

Could you kindly advise on how to resolve this issue and successfully enable the Advanced DLP features?

Thank you.
