Is it possible to disable Discourse updates?

I am not sure what exactly you are waiting for. The topic I linked already explains how to configure the version you want to install.

@Discourse

Follow these steps to configure the desired branch in your Discourse instance:

1. Access the configuration file
   Open the app.yml configuration file by running the following commands in your console:

cd /var/discourse
git pull
nano containers/app.yml

The nano editor will open the configuration file.
2. Edit the tracking branch
Locate the version parameter by searching for the word “version” in the file:

params:  
## Which Git revision should this container use? (default: latest)  
#version: latest

• Uncomment the version line.
• Replace latest with your desired branch or tag name (e.g., esr).Example:

params:  
## Which Git revision should this container use? (default: latest)  
version: esr  

3. Save and exit

• Press Ctrl+O to save your changes.
• Press Enter to confirm.
• Use Ctrl+X to exit the editor.

4. Rebuild the container
   Once the changes are made and saved, rebuild the container to apply the new configuration:

git pull
./launcher rebuild app

You said you don’t want the ESR version, but a specific one. But the same process applies whether you use a branch, tag, or a specific commit hash - you simply replace the value of version accordingly. You can also find some examples of that in the forum [1] [2]

I still recommend avoiding pinned commits in production, since you will not receive security updates or fixes unless you manually track them.
