Update contact-form-selector block apiVersion to 3

Hello, I’m building a new website using the Gutenberg editor, and I would like to utilize the new functionality of WordPress loading the editor as an iframe in the editor, but for this to work it needs all blocks to be apiVersion 3, so installing CF7 breaks this functionality and reverts block editor back to old style.
Is it possible to update it? as far as I know changing to apiVersion 3 won’t affect anything else, just it will enable iframed editor.
