It is compatible with 11, but it is likely that you won't have a driver for some of the hardware. Also if you have a software related problem, you won't get any help from Acer, as they support the pre-installed OS only.

Microsoft offers the ability to create your own Windows 11 installation media in case you want to install a fresh copy of Windows 11. This media will include all files for Windows 11 installation, but will not include all software that was preinstalled on your Acer computer. If you want to create media that includes Acer preinstalled software and drivers


Downloading Drivers:

Visit the Drivers and Manuals section of the Acer support website.
Enter your Serial Number/SNID or search for your product by Model.
Choose your Operating System.
Select Driver.
Locate the driver you want to download and click on the download link.
The file will be saved in your Downloads folder by default.

Installing Drivers:

Navigate to the folder where you downloaded the file.
Right-click the downloaded ZIP-file and then click Extract All Files. Double-click the folder that has the same name as the downloaded file.
Locate and double click the setup.exe or install.exe file you want to install.
Click Yes when prompted to allow the app to make changes to your PC.
