How to inject device property with clover

I am trying to inject device property for my Vega 56. I added the following fields under device

​

<key>Devices</key> <dict> <key>Properties</key> <dict> <key>PciRoot(0x2)/Pci(0x0,0x0)/Pci(0x0,0x0)/Pci(0x0,0x0)/Pci(0x0,0x0)</key> <dict> <key>ATY,DeviceName</key> <string>Vega 56</string> <key>ATY,FamilyName</key> <string>Radeon Pro</string> <key>CFG_NVV</key> <integer>2</integer> <key>CFG_PTPL2_CNT</key> <integer>16</integer> <key>CFG_PTPL2_MAX</key> <integer>300</integer> <key>CFG_PTPL2_MIN</key> <integer>90</integer> <key>CFG_TPS1S</key> <integer>1</integer> <key>model</key> <string>Radeon Pro Vega 56</string> </dict> </dict> 

The device path is copied from hackintools.

But I didn't find any differences before and after. Also, I set the model name to be "Radeon Pro Vega 56", but in "about this Mac", the name is still "Radeon RX Vega 56". In this case, does it mean that my injection failed?

​

Any help will be appreciated.
