Change hover colour on Navbar

How do I change the colour of the hover on the navbar? I know I can change the primary variable but that changes everything. I just want to either change the navbar mouseover/hover or disable it completely.

In my case use i change the variavel:

$header-light-toggler-icon-bg: url(“data:image/svg+xml;charset=utf8,%3Csvg viewBox=‘0 0 30 30’ xmlns=‘SVG namespace’%3E%3Cpath stroke=’#{$header-dark-color}’ stroke-width=‘2.25’ stroke-linecap=‘round’ stroke-miterlimit=‘10’ d=‘M4 7h22M4 15h22M4 23h22’/%3E%3C/svg%3E”) !default;

$header-light-toggler-hover-icon-bg: url(“data:image/svg+xml;charset=utf8,%3Csvg viewBox=‘0 0 30 30’ xmlns=‘SVG namespace’%3E%3Cpath stroke=’#{$header-dark-hover-color}’ stroke-width=‘2.25’ stroke-linecap=‘round’ stroke-miterlimit=‘10’ d=‘M4 7h22M4 15h22M4 23h22’/%3E%3C/svg%3E”) !default;
