Bootstrap gets better each version that comes out. Version 5.0 has a class that will work to remove any border-radius on an element.
Bootstrap has also adding gradient backgrounds in version 5.0
If the default styles do not work, then I would add a separate .css file.
or
Then apply the .new-gradient to the element you want!
