This EZCOO HDMI splitter will also do the job as well as let you customize the EDID:

Some folks use that splitter with home theater projectors to enable LLDV (player-led aka Low Latency Dolby Vision).
For more money and functionality, see the devices made by HDFury (mentioned at the end of the article). e.g. the Dr HDMI 4K:

There is no security inside the HDMI cable itself. It's an HDCP negotiation between the source and the sink which occurs over an i2c serial bus along the pair of DDC pins.
You may be able to get away with just an HDMI dummy plug:

I'm not sure if these dummy plugs handle HDCP. If not you can use one in combination with this splitter:

I own this splitter and know for a fact that it handles the HDCP negotiation. But I think it needs a display attached.
I use this HDMI splitter. It lets you either set a preprogrammed EDID, or learns an EDID from whatever you plug into HDMI output 1, and then shows up as a connected monitor for as long as the splitter's plugged in without having to connect anything to the outputs. I believe it negotiaties HDCP between the computer/console/whatever and the splitter, then sends the signal to the output monitor without HDCP. https://www.amazon.com/dp/B07VP37KMB
