You should remove the v-icon
directive from the <v-icon>
component:
<v-col cols="6" xs="12" md="2" lg="2" xl="2">
<span class="span_titulo">Valor Unitário:</span>
<div class="form-group m-1">
<v-text-field class="mt-0" type="text" maxlength="6" disabled v-model="form.vlrUnit" hide-details>
<template #append>
<v-icon :color="vlrUp === true ? 'red' : 'green'" left>
fa-solid
{{ vlrUp === true ? 'fa-turn-up' : vlrUp === false ? 'fa-turn-down' : 'fa-brazilian-real-sign' }}
</v-icon>
</template>
</v-text-field>
</div>
</v-col>
