Those rimless tank have added support between the glass and structure to begin with. Some even have the bottom framed liek mine does. It's all a matter of how it's put together.
I for sure 100% would not remove a brace on your tank. As mentioned it can only cause future or even immediate trouble.
Is there a way to re adjust your moonlights? Or move the lighting fixture or is it kinda stuck where it is? Would boosting up your lighting fixture help?

I have a mix of many different saltwater fish amongst my tanks, but I love my Tangs most of all.
