Unfortunately, I'm afraid those are likely dead-end cards. Looks like they've served their purpose but it may be time to cut bait. Especially that secured card, which unless Capital One changes their policy will never unsecure.
@Sz1 Capital One briefly experimented with the graduation of their secured cards but have since stopped.
There has been no clear answer from them if they will resume such practice again in the future or not.
It's been at least a year since they stopped , possibly longer.
I personally would not count on it, being that even in the past when they allowed it, it only involved cards opened during a certain period of time, so who knows if yours would fall in that range even if they resumed.
