[Plugin: WooCommerce] Change variation image without select all attributs

I have different products on my shop with 2 attribut (the color) which contains 3 terms and (the size) which contains 3 terms too.

I created different variations per product for each color and price attribut with custom image and price.

After that on the product page, which by default show the “Select a option” if we do not have defines the default selected value from the product variation settings, the default image is showing

I would like to have the white color selected by default(which I already configured as default value for the selected color) and then leave the “Choose a option” for the size attribute to let the customer select by him self the value

Now if I change the color value, the image won’t change, the variant image will change only if I select size value, mean that if all variations are not selected the image will not change

I thinks that there are some function do to it or some custom changes is required within the add-to-cart-variation.min.js and the wp-util.min.js file but I do not know where to start

Is there a way or solution to be able to change the image instead select all variations ? I saw lots of topic about that and I have tried several ways to make it work but was not able to do like I want

Any help would be appreciated
