Absolutely; use a password manager. This is the least bad way to go for these types of "security questions": give a plausible, but wrong, answer.

Correct is too easy to guess.

Obviously wrong will be recognised by the customer service representative, who is a kind person, and will help you out by just disabling the question (anecdotes galore for this, to the point we can call it data).

Lie, in a believable way. Put the answer in a password manager. Open your password manager up before calling any CS rep. Be a star in the security theatre. :)

Password managers solve the storage part of making security questions secure, but there's still the question of generating sufficiently random answers in the correct format.

I look forward to password managers including generators for your birth date, family tree, childhood friends, favorite color and maybe also social security number, name and address if those aren't actually required for anything. Then you can have a value for your mother's maiden name that isn't incredibly common, but nonetheless looks like an actual person's name.

I save my security questions in a password manager and just generate it. Though I've thought about instead giving answers that would serve as a message to customer service rep to actually validate it in cases of someone trying to impersonate me.
