While the service mode is needed and available on mobile workstations, a fixed workstation can be disconnected from AC power, then press and hold power button for 30 seconds to discharge residuary power. It will be ready for service works, no jumper is needed.

FYI:
5810 came w/o a service_mode jumper :-(
@JOcean
thx for the layout pic! 22 and 28 are not needed in this case.
@Chino de Oro
service_mode jumper is needed to backup the complete BIOS. Only in service_mode the whole code will be downloaded.
Good news:
NVMe boot (UEFI and legacy) is available w/o any BIOS modification.
The machine works very fast with a 1TB NVMe0
