Is there a way to do so?

Indeed there is, although I don't know if it is documented anywhere and how well. Found this here: https://steamcommunity.com/groups/SteamClientBeta/discussions/0/154644787621730542/

C:\>set SHIM_MCCOMPAT=0x800000001

C:\>your_program_to_launch.exe

If you replace 0x800000001 with 0x800000000, then this will become equivalent to choosing the “Integrated graphics” item. And an important note: this solution is almost certainly specific to NVIDIA Optimus, so you'll need something different for AMD GPUs.
