No, I don't think so.
I have been able to change the wheel cylinder by just taking one end off the 2 springs at the top centre, above the cylinder, and taking that plate off, & just spreading the shoes a bit

Alternatevly, I'm sure if you pull the axle out, you can get to the wheel cylinder without talking springs off.

Generally, by the time you need wheel cylinders, the rest of the brakes need attention

It might be possible (and I know why you don't want to take them off too!)

Open the bleed valve and squeeze the two push-pins fully back into the cylinder.
Unbolt the cylinder and move it fully to one side.
There might be enough room to get the other side push-pin out of the notch in the shoe. The cylinder should come free then but as mentioned above the 'spring hanger' plate might be in the way.
If you remove the two pins coming in from the backing plate which hold the shoes in place you can move the shoes/spring/adjuster group around a bit and even pull it out at a bit of an angle. It will still be held in place at the top by the springs and hanger. This might help but if you move this shoe 'assembly' too much it twists out of shape. This might allow the cylinder to come out at the side.
And the adjuster has around an inch of extension. If things are really close then you could try opening that up fully. Best to measure how long it was set at before you unscrew it to avoid having to readjust it later.
Then reverse the process to put the new one in.
A bit fiddly but easier than refitting the springs.
Good luck and try not to teach your neighbours new combinations of curse words!
