Delete icons

[Gurnisht]

Hi,
I have a redmi note 5a(7.1.2) and I have a problem trying to organize my icons.
I don't want a lot of the default icons which I can't delete permanently.
I drag them to the bottom right of the screen and they disappear, however every time I turn on the phone they come back. How can i prevent them from appearing again on my device?
Thanks

Install a different launcher from the play store and set it as default.
