What are the laptop specs? If it's dual GPU, you should be able to disable the discrete GPU (dGPU) through a SSDT patch. This assumes your integrated GPU (iGPU) is supported by OS X of course...

 

You'll have to extract your raw ACPI BIOS tables and post them. With Clover, you can do that by pressing F4 at Clover main menu. All extracted tables will then be saved to Clover/ACPI/origin folder of your EFI partition or EFI main folder, depending on your Clover installation.

Add this to your Config file

<key>Devices</key>
<dict>
    <key>AddProperties</key>
    <array>
        <dict>
            <key>Device</key>
            <string>IntelGFX</string>
            <key>Key</key>
            <string>AAPL,GfxYTile</string>
            <key>Value</key>
            <data>
            AQAAAA==
            </data>
        </dict>
    </array>
</dict>

or in Clover Configurator under Devices/Add Properties, add the following

 

Device = IntelGFX

Key      = AAPL,GfxYTile

Value   = 01000000
