At today's stage (beta 4), official support for Intel iGPUs in Mojave still starts at Ivy Bridge HD4000 with no support for HD3000. So l can only recommend you wait for 10.14. If you have further queries on Mojave beta, please head over to the section dedicated to that version or check the MacRumors thread on running Mojave on unsupported Macs. Thanks.

Update directly from the AppStore. Then remember to reboot the "install from ..." partition until update has completed. From experience, I can tell I had trouble with Clover r4586 (E6220 would reboot to black screen) whereas no issue with older version r4081 of my initial High Sierra USB installer + original E6220 EFI folder. boot_r4081.zip E6220_EFI.zip (minimised to E6220's applicable files)
