PCV metal hose removal?

[A80Avant]

Is there any easy way to remove the metal hose that goes from the cylinder head to the PCV valve in order to clean it?
I placed the flame deflector yesterday and realized that it could use some cleaning.Only the position where the EVAP valve connects i have no idea how to disconnect it in order to remove the whole thing from there and try to spray it/clean it as much as i can.
any input would be appreciated
thanks

I don't believe the metal hose is bracketed to the engine anywhere, but access is very tight at rear of engine. I want to remove mine sometime soon to size up the sections of rubber tube that make the various connections...

the metal hose actually is not,but some pictures i took a little while ago today show that the position of the EVAP valve connects to the metal tubing and also via a blastic smaller tube to the inlet manifold directly below the throttle body.
the problem is that all hoses are connected with metal clips that are without a bolt to unscrew but are clipped/tightened and those are bas!@$%^&@ to remove.I must have jubillee clips available to replace at the specified hose diameters

here is the photo i took
as you can see i need to at least cut the first of the 2 jubilee clips in order for the whole thing to be removed and taken off
