Nope. There are good reasons for blocking people from submitting answers to questions that are on hold. We want to make sure the question meets the site's quality standards before taking answers. We have lengthy experience that accepting answers to questions that don't yet meet the site's quality standards can create a mess.
For instance, when a question isn't clear, then people answering can create a mess, because they may answer based on their guesses at the question, but if that doesn't turn out to be a correct understanding, we can end up with multiple answers that aren't relevant to the asker. Or, answerers can waste their time answering a question that isn't what the poster really wanted to know. Or, if a question isn't clear about the problem requirements or how answers should be evaluated, then it can be difficult for readers to vote on any existing answers.
The site generally works better when questions are in a good shape before people start to write answers. That's not something that can always be enforced perfectly, but the system is designed to nudge you towards that ideal.
If a question is put on hold, then normally there is a reason for that. The best response is to understand why it was put on hold. If it was a duplicate, then answer the other question. If you can fix the issues in the post, then you might consider editing the question to make it suitable for our site format, or leaving a comment to ask the author to fix it, or post your own version of the question that is better formulated, or just move along and answer some other question. If you are not able to address the issues, then it's best to avoid answering until the issues are resolved.
Caveat: If you are considering editing the question, be prepared that on this site, this might not be received well. Some people here believe it is important that the original poster make any changes that need to be made. So, it is generally safer to avoid editing and to avoid answering until the issues with the question have been addressed, if you want to minimize the chance of wasting your time.
