[Feature] Remove the protection background grain by configuring

[zhao-bin-zero]

Initial checklist

• Is this really a problem?
• I have searched the Github Issues for similar issues, but did not find anything.

Problem

My requirement is to disable most of the cells in an excel workbook, and only some of the whitelist cells can be edited (they will have their own background color). If there is a gray background, it will be very ugly, so the request can be determined by some configuration whether to add a background.

Perhaps users can be allowed to configure whether to display mask @ybzky.
