Can we hide a line item subtitle with cart transform?

[Benny_Chan]

I am using the cart transformation - expand operation now. Following the optional add-on js example, I can change the title like this:
title: ${merchandise.title} with warranty,

But this line only change the title. I want to hide the subtitle (i.e the variant title). Can I change/hide it as well? Is there any way I can do so?

By subtitle, do you mean the title of the variant that is shown on the checkout (as highlighted in the image)?

Yes, I mean the variant title
