Litespeed optimization further safe options?

Hello, I am trying to optimize the website performance, I have followed your guide.

On page speed tests, I get low score for mobile

Using litespeed plugin, is it safe to enable:

Generate UCSS
UCSS Inline

Experts profile image dont have width e height explicit , can I change that using the option:

Add Missing Sizes?

Also, is it safe to HTML Minify ?

All these options are available on Litespeed but are not enabled on your tutorial. Are they safe?

Thank you

Yes, they are safe if you define image sizes, HTML modification may affect some spacing - I recommend checking the layouts after enabling it.
