Enable advance option in bios setting

Let's start by confirming virtualisation is supported by your CPU (it's a given you'll also need at least 4GB of RAM). To do this, press Ctrl+Alt+Del keys and select Task Manager from the menu, click the Performance tab and then select CPU. "Virtualization" entry should be enabled. You can also:

* download AMD Virtualization Technology and Microsoft Hyper-V System Compatibility Check Utility. After unzipping the file, run amdvhyperv.exe and see the result.

* use other system info software of your choice, like Speccy or SecurAble(portable) etc.

Next, let's see if it is possible to enable it from your BIOS, here's some fixes some users on Acer forums reported to work:

• on BIOS v1.31, enter it and hit Ctrl+S combo on all tabs to reveal hidden options if there's any (ref.)
• Press and hold Fn & Tab Key for 3 Seconds, then press and turn on the PC and hit F2 repeatedly until you get to the Bios. An Advanced Tab should appear and after entering CPU Settings you should see the Enable SVM option (ref.)
• You probably also noticed the tutorial in this video, as it implies tinkering with bios binary values it's not something I would personally recommend, but of course you're free to try it just remember it could potentially brick your laptop so use caution.

Note that a machine running Win 10 Pro/Edu/Enterprise is required in order to use Hyper-v(MS's virtualization platform). Now the problem is, on modern Windows OS, Hyper-V tends to disable VT-x / AMD-V by default to avoid conflicts with programs like VirtualBox & VMware, also some Windows features could be preventing you from normally running your virtualization software, as they give priority to hyper-v over AMD-v; VirtualBox 6.1.x for example now requires VT-x/AMD-v to be available, for more insight check out this topic. So If you're experiencing problems you should disable Hyper-v (just run "appwiz.cpl" to access the Windows features menu and un-check it) in case you wanna run VB or similar; you can also try out Windows Hypervisor Platform, which supposedly will allow you to run VirtualBox even with Hyper-v still on.

Finally, if the problem persists you can contact Acer Support centre and expose the issue to see if they can help you.
