To install Bluestacks while bypassing the graphics card requirement, a user needs to download a modified client or a way to edit it by himself. You can access Google Search because there are pre-made clients available for this operation as well as tutorials on how to modify the package. For example, you can use Techempty's website to download a copy of a modified package or TrickyWays to learn how to edit the MSI file with Orca. These are the only options available.
