Shinrarta Dehzra is a hot spot for gankers. On the inara.cz galaxy security report (top left) you can see where the hot spots are. Usually there are around 10 of them. Systems with active Community Goals and some systems with engineers in them (Deciat) are always on the list. The inhabited bubble has around 20,000 systems so 10 in 20,000 shows how low the chance of running into gankers actually is. You can play in open for months or even years without running into any.
To be fair, the inara.cz list also includes normal competitive PvP activity like in the San Tu system. If you jump into such a system you are fairly safe because those players usually inquire via chat if you're in for a fight and will not engage if you decline.
My advice is to be pragmatic about it. If you don't want to waste time dealing with gankers, simply switch to solo or a private group one jump before reaching a hot spot, do your business there, jump out and switch back to open.
