Can a SASS mixin edit a @content block?

Question

In my current app, I'm importing a lot of SASS stylesheets from a well known library which all look like this:

.v-application
  @each $name, $weight in $font-weights
    .font-weight
      &-#{$name}
        font-weight: $weight !important

  .font-italic
    font-style: italic !important

.v-application
  @each $name, $bezier in $transition
    .transition-#{$name}
      transition: 0.3s $bezier !important

Right now, all these stylesheets are passed in a mixin which looks like this (this file is not imported from the library so I can edit it)

=media-breakpoint-up($name, $breakpoints: $grid-breakpoints)
  $min: breakpoint-min($name, $breakpoints)
  @if $min
    @media (min-width: $min)
      @content
  @else
    @content

Now, what I'm trying to do is to edit the @content blocks to remove the parent .v-application in all stylesheets.

I cannot edit the imported stylesheets directly, I can only edit the mixin. Is it even possible?

Sorry for this weird request, and thank you.
