There are some great examples on here: https://bootstrap-vue.org/docs/components/form-select they talk you through the different ways of setting default values.
To disable your placeholder value all you have to do is this:
:options="[{ value: null, text: 'Select One', disabled: true }, 'ALTiPROSJEKT AS', 'AiP BETONGSAGING AS', 'AiP ENTREPENØR AS', 'AiP SANERING AS', 'AiP UTLEIE AS']"
