Belief isn't a choice. But you can evaluate and apply methods for determining what's true, which can lead you to believing something is true. And you can choose to question something, which can create doubt, and which can ultimately change beliefs if you reevaluate your reasons for believing.
This doesn't allow you to believe whatever you choose though. You probably can't start believing there's an invisible unicorn in your backyard, no matter how much you (responsibly and consistently) doubt and reevaluate, but that would be "working as intended" to avoid unjustified beliefs.
Along those lines, I have, on occasion, heard something along the lines of "your standards of evidence is too high, because none of the available evidence would convince you that this true claim is true". The obvious response is that claim would be an unjustified belief; none of the available evidence would convince me of that conclusion because the available evidence doesn't point to that conclusion (as per my best judgement, which of course isn't perfect). To convince me of the conclusion, someone would need to present a method for determining what's true, that would lead to said conclusion, and convince me that said method should be trusted. Or they would need to point out a flaw in the method I use (apart from not leading to a conclusion which they believe is true... which could equally well indicate a flaw in their method).
Whether someone claims to follow a system of inference doesn't mean they actually follow it. If something isn't consistent with their claimed system of inference for that specific belief, either they're lying or (more likely) they aren't being perfectly rational and may be blinded by bias (no-one is perfectly rational, but we can realise that and try to account for it through skeptical analysis of our beliefs).
Given that you tagged this with "free will", I'll just point out that this is a separate (but related) issue. That would be a question of what it even means to "choose" something, whether you can, strictly speaking, "choose" something. Although I suppose one could reframe part of free will as "I believe this action will best satisfy my desires", and then one might say you only do things you believe will best satisfy your desires. Note that this is using "desires" in the broadest possible sense: hedonistic desires, sure, but also desires to help others, desires to be have beliefs that match reality, desires to see justice served, etc.
