If they are dropping, then I'm assuming they are dropping due to hitting two years old? If so, then there's no FICO impact because FICO will not score any inquiry beyond one year old. Some FAKOs still score inquiries beyond a year though.
If you meant that they'll turn a year old in March, then likely not since the damage faded over the past year. Definitely not if you have other inquries inside a year still. However, some have experienced FICO increases as the new accounts behind those inquiries hit a year old.
