如何在WordPress上删除WooCommerce变体清除操作和默认值

I'm setting up a WooCommerce page on WordPress and I'm trying to hide the clear box action when you select a variation of the product.

I'm also trying to remove the "choose an option" choice from the variation list.

Looked online for tutorials and it seems like they're using outdated versions of WordPress. Asking me to go onto Admin > Appearance > Customizer > Woocommerce > Single Product > Additional Information Tab and there is no Single Product option.

Clear box action

Choose an option

Thanks.

SM.
