I looked in Acer's web site for the proper drivers for your system, please get in contact directly with Acer to gather the instruction to update the BIOS to the latest version, 1.22 and install Chipset driver version 10.1.1. This problem could be related to the chipset, the BIOS version the drivers or even the Operating System. Keep in mind that the OEM (Original Equipment Manufacturer) creates a lot of customizations on their laptop, they can enabled/diabled features and functions of the device. There are some reports that state, as you mentioned, that the Virtualization feature is enabled in the BIOS but the Intel® Processor Identification Utility shows is deisabled, that could be because of the version of the tool installed, please updated it to :

Just to confirm the Intel® Core™ i7-7700HQ Processor does support Virtualization, both (VT-x) and (VT-d) as you can confirm in the following link: When you play high-demand games, configure your computer on 4 Cores CPU and 4096M RAM. Click the save button to apply and finish the reconfiguration. Select the CPU and RAM allocation values to set the RAM and CPU usage. Mjfneto, Thank you for posting in the Intel® Communities Support. Open LDPlayer and go to the settings menu and then click advanced settings.
