Lookup fields are not supported in conditional formulas in SharePoint.

Source: can we show a column in a form based on a lookup field?

Avi65 Unfortunately, not possible using SharePoint JSON formatting.

You have to customize the list form using Power Apps for such requirements. Check: Customize a Microsoft Lists or SharePoint form by using Power Apps - easy & quicker solution

You can also build your own custom form using SPFx Form customizer. Check: Build your first Form customizer extension

@hanks for clarification again.

I visited your blog see following header, The yellow highlighted text in top bar, Is there any way to yellow highlighted text. I know it is title of Hub Site, is there any way to change with different text, so it should display for all the site collection. Secondly if see red box below and other navigation, in my case it is showing under images, not in same line, how can I also make it in one line.
