In the EU it’s known as being an “Experienced Investor”
You can self-certify that you meet the EU Experienced Investor Rules and get access to US ETFs without the KIIDs (ETFs currently would fall under the UCITS banner therefore have KIIDs as opposed to KIDs under PRIIPs. ETCs do however fall under PRIIPs - just to confuse matters!). Either way, yes, there is a workaround. I’ve been buying US ETFs on other platforms and it works fine (sort of - had a few issues!)
