NO BUG: Bug, but not in Bricks. How could I deactivate plugins in Bricks editor?

Not the same thing, but would this help?

Otherwise, there is a PHP condition

if ( is_bricks_builder_main ) { we’re in the builder }
if ( !is_bricks_builder_main ) { We’re not in builder }

I’m afraid I’m not sure how you’d unhook the encoder with this… but maybe their support could suggest something.
