At least some do - Rolec, PodPoint, Zappi(v2) are ones I know for sure claim this capability.
Unfortunately, that's ambiguous - a chargepoint without DC protection can be installed in compliance with 18th Edition regulations, simply (and expensively) by using an external Type-B or Type-EV RCD.
I was trying to see if the EO units fall in this category. On the website they now say "18th Edition IET Wiring Compliant", but appear to have deleted the full datasheet from their website (Google finds it but the link is broken). On another
website there is a copy of the datasheet, dated March 2018, which makes clear that if you require DC protection you need to fit an external RCD. So have they updated the product, or do they comply via an external RCD?
PS. your spreadsheet says that the EO units don't do loadsharing - that seems not to be true as they sell an add-on box to do the load sharing, though exactly what the spec is I can't say as there's no datasheet....
