I fear I would be wasting my breath, @Michal_S. @Rob_P asked them this same question earlier this year. I refer you you to Samsung R32 ASHPs - when is a defrost not a defrost? - #9 by Rob_P for their response - a resounding NO…
What I will do is ask my contact (Nick, not Steve) what the procedure is for getting a technical request (from a large number of users) routed to Samsung HQ, as the UK helpdesk are themselves fairly powerless.
