To use networked iLO in Microserver Gen10 Plus an additional NIC card is required (p/n P13788-B21). If you don't have this card shared port will be also disabled.
TL,DR: pin B31 of MS10plus iLO dedicated NIC slot is used for addon card detection. Pulling this pin low (to GND) enables iLO network functions. Of course, it's only possible to use shared port iLO (port 1 or port 2 of 1Gb LOM) if you don't have an addon card.
This method was tested with iLO 2.16 and System ROM 2.16. Future versions may improve PHY detection routines to disable this easy activation.
If you want to do this hardware modification you'll need to either solder a short wire between pins B31 and B32 of iLO dedicated slot on MS10 Plus's riser card (reliable and preferred way) or insert a jumper wire between these contacts. Any hardware modifications are risky and you only doing that at your own risk! Also I think your warranty will be void if you'll do any soldering to the riser board.
If you want to try this mod, I strongly advise to go with soldering method. Stray jumper wire may break, detach or fall off and short/damage/fire up your system board!!! Extreme care must be taken if you only want to insert a jumper but not to solder it.
Fully remove power before doing this mod. iLO must be reset after applying or removing the mod for changes to take effect.
To solder: remove the PCIe riser and unscrew riser's PCB from it's hardware. Solder a thin wire on the back of dedicated slot between B31 and B32. Assembly everything back. Any soldering will void your warranty!
To insert jumper: push spring contacts with an egde of any card and insert a piece of thin wire between B31 and B32. Make sure spring contact holds your wire tight so it won't fall down to your system board causing shorts, smoke and havoc. Pin pitch is only 1mm so it's easier to remove the riser and insert the jumper on your bench. Don't try just to instert a wire into free space above the spring contact! The wire will fall off and damage your board. Make sure spring pin actually holds the wire in its place. Double check for errors and shorts! If possible, use the soldering method as it's much more reliable.
If the jumper wire connects properly, you'll see iLO IPV4 and IPV6 information no longer says "Disabled". Go to system configuration and configure iLO to use LOM shared port. Have fun!
