Get sxa component rendering parameter into variant data-attribute field

Question

I'm currently trying to get rendering parameters from a component into a variant data-attribute, is this possible ootb in sitecore 9.3 ? I heard about Scriban but i'm still new to that.

For example:

I have a Link component wich i added a parameter, this component is using a Variant where i need to fill the Data Attribute Field with the value of this parameter like shown in the image bellow.

May i ask why do you need it from rendering parameters not from the datasource. If you can put the field in the datasource you can just use $(Background Image) where background image is the field.

If it's absolutely necessary to make it from rendering parameters the best way i can think of is to override GetAttributeTokenValue and create your own attribute for that rendering parameter.

Something like the below

public class RenderVariantField : Sitecore.XA.Foundation.RenderingVariants.Pipelines.RenderVariantField.RenderVariantField
{
    protected override string GetAttributeTokenValue(string fieldName, Item item)
    {
        if (fieldName.Equals("mgen_value"))
        {
            return //get valur from rendering parameters
        }
        else
        {
            return base.GetAttributeTokenValue(fieldName, item);
        }
    }
}
