I have considered physical coins like a Casascius coin.
What I understood about Casascius bitcoin is that the minimum available is 1 BTC, that is not just a small value today, not knowing the exact amount that you wants to gift to your friend, but Casascius bitcoin price is not flexible at all, it may not be a good option, I guess. Even in my country, I can buy a very beautiful house with 1 BTC. Although, I do not know the purchasing power in your country.
Also, maybe because of where I am residing, Casascius bitcoin will have to be shipped to my country or something like that, I have not gotten one before but likely will be what will happen. So, if no one to sell in the country you are residing could be another obstacle.
I do not think that gifting any kind of Bitcoin-related gifts such as hardware wallets, or Bitcoin gifts will be useful because he is not interested in technology and will forget those wallet seed or not remember the location of the device.
I have a brother that is not interested in bitcoin all because he is afraid not to lose the coin as he will have the whole responsibilities of protecting the coin, but he knows its worth, if I want to give him bitcoin today, he will gladly collect it and use it for something. The reason why some people do not just like bitcoin is because they do not know much about it and hearing about how some people lost their coin, but they know its worth. I believe almost everyone knows bitcoin now, and the worst he can do is to sell it. I think there is nothing bad to gift a friend bitcoin and making him realize its worth. Just my opinion, but your idea will be pleasant to his friend, it is good to gift what the friend will more appropriate.
