Best Practice to override a mixin

I have to customize a form layout light that have the mixin in api valo.

@mixin valo-formlayout-light-style($row-height: $v-unit-size)
{

table { padding: 0; } > table > tbody > tr > td { padding-top: 0; height: $row-height; // Effectively min-height border-bottom: valo-border($color: $v-app-background-color, $strength: 0.3);
… … …

How is the best practice to do that.

copy and change name?
