As a former Probook Installer user (depreciated);
...Wanted to confirm that by following the Rehabman guide
everything works, except HDMI out [expected], and sleep/hibernate[expected]
No more RTC/CMOS reset issue w/ proper power management implementation...
... and (AppleRTC flag in Clover [unneeded?])
----------
Same Configuration as OP,
(RehabMan's HotPatch Method)
HP Probook 450 G4 i7 (Clover)
Intel HD620 Graphics
Mac OS: Sierra 10.13.5

Processor Name: Intel Core i7
Processor Speed: 2.7 GHz
Number of Processors: 1
Total Number of Cores: 2
L2 Cache (per Core): 256 KB
L3 Cache: 4 MB

Works . . .
Bluetooth (works)
Connexant Audio (works)
1080p Display/Brightness (works) [changed config.plist to 1920x1080 for clover boot menu res.]
SMBIOS
MacBookPro14,3
What's Not Working . . .
HDMI Video/Audio (disabled by default...[Kaby Lake limitation?])
Solved Issues . . .
Shutdown/Reboot (works fine)
CMOS Reset Fixed by proper ACPI/AppleRTC flag (clover configurator)

It is worth the time and effort to follow the Rehabman guide for any of the supported HP Probook/Elitebook/etc line of notebooks.
...all modifications are visible in terminal and updates (so far) are simply a two reboot process.
(Also check APFS.efi for updates, run the install script)

The only odd issue that I encounter is while viewing youtube/web videos in full screen (occasionally) videos blank/black out after the mouse cursor timeout....(audio still plays)...moving the cursor in full screen shows the video again until the mouse cursor timeout.
This only happens in full screen (occasionally), and I believe it is something to do with the video not being in 1080p (this is only web videos) and does not apply to downloaded videos or applications.
This is a minor inconvenience but any insight is appreciated.
