I used to line the shower or tub with several layers of cardboard (from appliance boxes), put a painter's tarp over the top to catch glass, remove the shower doors and replace with draped painter's tarp, then (wearing face shield AND safety goggles and heavy leather welding gloves or Kevlar cut-resistant butchers gloves), use a 6 inch broad chisel and soft weighted hammer (to avoid shattering glass all over if I missed, as would happen with metal hammer), work from top down driving the chisel between blocks and the concrete or backer board they are bonded to. Usually pop free pretty easy, especially if grouted as opposed to installed with construction adhesive, so you can catch them before they drop. To minimize risk of dropping and damaging tub/other tile, duct taping across them diagonally both ways before starting helps a lot - can prevent any full-block from falling.

Generally do not break too badly - but get a tight one or one carrying stress and they can almost explode - hence the gloves and face/eye protection.

If a window - run a sawzall blade or free hacksaw blade around the outside through the grout or mastic to free them up, also through a center joint each way if needed to create enough free space, then after double-sided taping cardboard over the inside and outside faces, press through - basically "extrude" to someone on the outside waiting to catch it.

If needing to cut only some out, cut through the joint with diamond blade or sawzall blade.

Look closely before you start - some used a slide-in frame design, so you just pop the grout or caulk out with a grout removal tool and then pull the blocks out one at a time - suction cup might help a lot if that is the case - will have to wet it to grip, and will not grip if rough glass type - double sized tape might work in that case.
