I'm not sure what you expect from us. Yes, HCl corrodes metals. Yes, HCl will probably corrode circuit boards. Yes HCl is volatile and yes the fumes are also corrosive. No, you shouldn't use HCl in a poorly ventilated space because it could damage your electronic equipment over time, or your lungs. That said, Yes, we do use HCl in chemistry labs, and Yes we often have computers and electronic equipment in labs. But labs are also designed with good ventilation. So No, it's not necessarily a comparable situation.
You are asking for a yes or no answer to a question that depends on a lot of factors, including how much HCl you are using, the concentration, the frequency, the amount and type of circuitry boards you have and where they're stored, and the air-movement characteristics of the space you're working in. Impossible to answer your question in a black or white way probably even if we knew all these details.
Is the risk to your boards in the short term high? Probably not. But if you don't want your circuit boards degraded, or some kind of chronic long disease, don't use HCl inside your home in an unventilated space. That's the only way to be sure and I'm not sure what else any of us can add.
