From what I see from several answers, I may not have explained myself well. Going on vacation and carrying less than the legal minimum is not a problem. I was thinking more of moving to another country, and taking the holdings you normally manage with your Hardware Wallet on your laptop or PC.

I mean, carrying 0.01 BTC on your mobile is not a problem but if we are talking about 0.5 BTC that you manage with the HW....

Although I see that this is pretty hypothetical, according to the answers.

I had also thought of taking the seeds written in a book or notebook on several pages, but with invisible ink, so that no way that it will occur to customs agents to search through a book of 300 pages.
