How to remove TYPOGRAPHY section from style.css file?

Hi,
I need your help. The biggest problem is white rectangle when A tag is :focus’ed. I found the reason and now I would like to remove below lines from style.css:

.single-post:not(.elementor-page) .entry-content a:not(.wp-block-button__link):not(.wp-block-file__button),
.page:not(.elementor-page):not(.woocommerce-page) .entry a:not(.wp-block-button__link):not(.wp-block-file__button) {
  cursor: pointer;
  text-underline-offset: 3px;
  text-decoration: underline;
  text-decoration-skip-ink: all;
  transition: all 0.3s ease;
}

.single-post:not(.elementor-page) .entry-content a:not(.wp-block-button__link):not(.wp-block-file__button):hover,
.page:not(.elementor-page):not(.woocommerce-page) .entry a:not(.wp-block-button__link):not(.wp-block-file__button):hover {
  text-decoration: underline;
  -webkit-text-decoration-style: dotted;
          text-decoration-style: dotted;
  text-decoration-skip-ink: none;
  transition: all 0.3s ease;
}

.single-post:not(.elementor-page) .entry-content a:not(.wp-block-button__link):not(.wp-block-file__button):focus:not(.wp-block-button__link):not(.wp-block-file__button),
.page:not(.elementor-page):not(.woocommerce-page) .entry a:not(.wp-block-button__link):not(.wp-block-file__button):focus:not(.wp-block-button__link):not(.wp-block-file__button) {
  /* Only visible in Windows High Contrast mode */
  outline: 2px solid transparent;
  text-decoration: underline 1px dotted #13aff0;
  text-decoration-skip-ink: none;
  background: rgba(255, 255, 255, 0.9);
  transition: all 0.3s ease;
}

Any idea how to do that? I’m using child theme. Maybe is possible to remove this section using functions.php file?
