HP Recommended

I have a HP ProOne 440 G9 23.8” Business All-in-One – Core™ i7 which I bought spring 2022 - within 6 months and for no apparent reason it stopped booting with the 'sure start detected an unauthorized change to the secure boot keys' error - tried the customer support but they told me to contact tech support - who I could never get through to on the phone - so anyway the warranties expired and I'm now stuck with a £1k machine that's no better than a very expensive paperweight!  I've even taken it to a local 'computer shop' and they've said they can't do anything with it.  I've tried every 'help' option I can find by googling the error (which seems quite common but I haven't, as yet, found anyone who's actually fixed the issue) - so before I take a hammer to the **bleep** thing and promise myself never to get an HP again - is there a fix, workaround, overwrite or ANYTHING I can do to get this working again? thanks
