Lelit Bianca V3 - is the Solenoid valve adjustable, DIY upgrade?

Need help with equipment usage or want to share your latest discovery?

Hoping the valve is adjustable. From the videos from Lelit it doesn't seem to be, but I don't have one to take apart. I did some searching on their parts diagram and it looks like basically a dual circuit solenoid, ie one for low flow and one for normal flow. I cannot find a pic of the US spec part, the European one is pictured here:

If not, I would assume one could basically take two full flow solenoids and put a needle valve after one and fundamentally mod their E61 into slayer like adjustability?

Asking as I am contemplating either upgrading my machine with some DIY mods or replacing it. For the SO I need something "automated" and not another lever to pull. Couldn't find any details on what Lelit is doing and figured I am not the only one who is interested.

Looks like it's a binary choice of either full opened or full closed but I like the idea of an inline needle valve.

Based on the 1st line video I just saw the second solenoid is for returning water to the steam boiler. I would assume then this isn't related to the low flow setting. Curious how it is done? Anyone have thoughts?
