Is a Bank of America credit limit increase a soft pull?

Yes, you get a Bank of America credit limit increase with a soft pull on your credit.

It is worth noting that Bank of America doesn’t give automatic credit line increases, so you will have to apply for it.

You can request a credit limit increase every six months. But, unless there’s been a change in your financial circumstances, like a pay raise or a debt paid off, you’re unlikely to get one more than once a year.

A soft credit check will be listed on your full credit report, but it won’t have any effect on your credit score.

Unfortunately, they're gonna be hard inquiries, since they don't automatically increase your credit.

Usually, lenders will do  a soft pull only when they decide to increase the limit on their own.
