Howdy Leah,
That is certainly possible. The easiest way would probably be to create a theme override by following our Themer’s Guide. The file you would want to override would be the modules\tickets.php file. You might just copy/paste the following snippet into [your-theme]/tribe-events/community-tickets/modules/tickets.php
https://gist.github.com/elimn/9270713f8539e3bd8178d35759d9b79a
From there find the line that says:
$checked = $module === 'WooCommerce';
And change it to:
if ( $module !== 'WooCommerce' ) continue;
That should show only WooCommerce. The original snippet I shared sets Woo to the default, but this will completely hide the other options.
Does that all make sense? Will that work for you? Please let me know.
Cheers!
