Hi and welcome. I couldn't find a solution on roll back unless you have Timeshift installed, but did find solution on how to prevent updates with Brave A.I. search engine via mojeek:
"To prevent updates from occurring, you can pin your packages to a specific version using apt . For example, you can use the apt-mark command to hold packages from being updated:
sudo apt-mark hold <package_name>
Replace <package_name> with the name of the package you want to prevent from updating. To unhold a package, you can use:
sudo apt-mark unhold <package_name>
For the MegaRAID driver, you would need to find the specific package name and pin it to the version you want to keep. However, this method does not prevent system-wide updates, only specific packages.
To manage the MegaRAID driver specifically, you can also download and install the specific version of the driver you need from the manufacturer's website or a trusted repository, ensuring it remains unchanged during system updates."
