So it's worth repeating the basics -
1) ensure you have set the SIP security to a level that allows third-party kexts to install and run:
Code:
<key>RtVariables</key>
<dict>
<key>BooterConfig</key>
<string>0x28</string>
<key>CsrActiveConfig</key>
<string>0x67</string>
</dict>

Clover Configurator to add the keys instead.
2) for NoVPAJpeg.kext you ALSO need Lilu.kext, as it is now a plug-in for Lilu. Check you have both latest versions.
3) if you are worried about kext cache rebuilding when you install to Library/Extensions, you can always do your testing by placing the kext pair in EFI/CLOVER/kexts/Other instead ...
4) If you choose to do this remove them from L/E first and rebuild the caches using Terminal and the command:
