All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger.
There is no doubt that the position of the father is great, and that whatever the child is able to honor him is a good thing, whether it is something that must be obeyed or not.
The child does not have to obey his parents if they order him to eat a specific thing or prevent him from eating a certain thing that does not result in harm from eating it, as decided by scholars, because preventing him in this case, is not reasonable.
You should strive to gain your father's satisfaction and try to convince him, even if it is through those close to him, whether relatives or friends, to combine the two benefits.
Allah knows best.
