How can I remove the white outline from my image banner button?

Hi! I need to make a botton at the Image banner #9176C0 this color fully with white text. I did it though the code

a.button.button–primary {
background-color: #9176c0 !important;
border-color: #9176c0 !important;
color: white;
}

it works bur it is also appear white outline around it. I want to take it away. If I do it through the button settings in the theme settings and put the opacity 0, then in the product card the outline in the add to cart button dissapere.
How it is possible to take away the white outline in the Image banner button?

Thanks!
