have set the settings in BIOS on UEFI. The board boot is slow and there seems to be no USB keyboard support. Thus you can not get into the bios and reset the settings back.

The described methods to reset the bios unfortunately do not work.
I assumed that there is always a possibility of resetting the BIOS, as it is possible to get the initial values ​​on every modern board.
It will require documentation from the manufacturer, what differences the board Delta has to Alpha and how to reset the BIOS without sending the board to China.
It must be ensured in the bios that always the keyboard support is active and that you can just reset. The board is aimed at different players, so it must also be ensured that you can handle the board like any other Intel CPU board.

Please show a way on how the board can be used again. I have an M2 SSD here and would like to implement my mini NAS @lattepanda delta with debian.

Many Thanks

Thanks for the test, but with my USB keyboard and USB BT keyboard it does not seem to work. No character can be entered in the UEFI Shell (see picture). The USB ports have power that I have also tested with a USB CDROM drive. But it seems the USB keyboard support in the BIOS to be inactive. With the mouse and the keyboard not a single light shines !! Thus one can not adjust the Bios unfortunately! That's my problem!

No light shining usually indicates no power, which means probably faulty hardware

Modifying BIOS settings can be a dangerous exercise, especially on selected fields (e.g., disable USB, disable HDMI, etc.)
Other than the removing the RTC battery (and trying to trick the BIOS reset itself to default configuration) or reflash the BIOS (thru BIOS SPI port), and the one in the very bottom (** might work)
I am not aware of other tricks.
Folks, feel free to share your tricks.

** this trick may or may not work:
- step 1. use the PCIe to M.2 key-M adapter (to bring out PCIe bus)
- step 1a, make sure 12V DC power is applied to the adapter (step 1) above
- step 2, find a standard sized PCIe based USB2 (such as VL6212 based) or PCIe based USB3 (such as Renesas based) adapter to get USB2 or USB3 port, assuming these are not under BIOS setting controls
- step 3, plug that card to the step 1 adapter board
- step 4, plug the USB keyboard on the USB2 port of the (step 3) card
- step 5, try the F3, <enter>, F4, <enter> procedure to reset BIOS to default

Removing rtc battery does nothing on a delta as the settings aren't battery backed

Thanks for the suggestions. I already tried it with a USB-C hub. No keyboard input is possible here either. I think the trick with PCIe to M.2 key-M adapter will not work either. The two USB Tastauren are with me at the other computers in the daily use. A defect of the keyboards I can thus exclude. Unfortunately, I have to swap the device. Unfortunately, there is no other way to get into the bios. It is a pity that you can not reset the bios settings just like a normal PC. Battery out or jumper set and you're on the factory settings.
Let's hope that the exchange works and the new Delta is not incapacitated after 2 days.
