Disable the insertion data until bluetooth connection is estabilished

Goodmorning everyone.
I wanted to know if it is possible to "disable" the insertion of data or check boxes on the initial screen until the bluetooth connection is established? Do I have to do it for every single writing box or is it possible with a single block?
I made an initial screen that shows the data stored in the last use as "suggestions" in the text boxes and I would like to be able to change them only after the bluetooth connection is established. It's possible?
Thank you
PS: In the indicated block I have to "disable" every single component. Is that how it works?

You could put all those components in an Arrangement, and set the Arrangement to Visible on connection, invisible otherwise.

Thanks ABG,
for the quick response, I actually put the "variable" blocks in this double arrangement and it works. I also had to change the background color because when they were deactivated the contents of the text box were not visible .. how much light gray.
Thanks again
