XF 2.2 How to hide a widget in a specific forum

[Soyuz_new]

Hello! I'm trying to hide the "similar threads" block in a specific forum (node id 150), but I don't know the right syntax. I'm putting this in the "Show condition" field of the widget:

{$xf.node.id} != '150'

$xf.reply.containerKey != 'node-150'

Thank you so much!
