Yes, GBWhatsApp, which is a modified version of the original WhatsApp application, offers additional features compared to the official WhatsApp. One of these features is the ability to hide specific chats. If you're using GBWhatsApp, you can follow these steps to hide specific chats:

Open GBWhatsApp: Launch the GB WhatsApp apk on your device.

Navigate to Chats: Go to the main chats screen where all your conversations are listed.

Select Chat: Long-press on the chat that you want to hide. This will highlight the chat and open a toolbar at the top of the screen.

Hide Chat: Once the chat is selected, tap on the three-dot menu icon at the top-right corner of the screen. From the menu that appears, select "Hide."

Set Password or Pattern: GBWhatsApp will ask you to set a password or pattern to protect your hidden chats. This adds an extra layer of security to ensure that only you can access the hidden chats.

Confirm: After setting the password or pattern, confirm it. Your selected chat will now be hidden.

Please note that the steps might vary slightly depending on the version of GBWhatsApp you're using, as different versions might have slightly different interfaces and options.
