Information for purchase

Hi, I’m evaluating the purchase of the plugin for an e-commerce project but I need the plugin to allow the user to insert multiple sentences into a predefined round diagram. Let me explain: the website I will create will be a jewelry store that wants to customize the writing of a ring. The customer therefore wants the user to just write the sentence and the plugin puts it on the ring, without giving him the possibility of modifying anything, just insert the writing. No other image uploads or anything.

Is it possible therefore to block all these features?
Hello and thanks
