Disable "Switch to Plain Text" on a Rich Text Field

Disable "Switch to Plain Text" on a Rich Text Field

I have a rich text with all the toolbar options disabled. I do this because on load I am setting some default values that utilize html tags to create a predefined data entry template/guide for my users.

Is there anyway to disable the "Plain Text" toggle option? I just essentially want a multi line field that can render html tags such as bold, pre, etc
