I always think of pyracanthas as growing in sun or dappled shade. However, I think they will grow in shade but maybe not flower quite so well.......so less berries.
comcern for,me though is your,neighbour......pyracantha is vigorously thorny so will project this foliage his/her way. No fun in pruning them.
Cotoneaster horizontallis may be a better choice. Berries well and shade tolerant.
