Question How do I change the New Input System Local Coop change control scheme?

Hi, I'm doing a 2-player game with the new entry system. I don't create my first player, it's always on stage, my second player shows up with a button. I want to build an access system like I drew below.

I have 3 different input actions :
Player = all keyboard and gamepad
player1 = left half of keyboard
player2=right half of keyboard

P1 - P2 = half of the keyboard is within two -- İnput Actions = "player1" and "player2"
P1 - P2 = two different gamepads -- İnput Actions = "Player"
P1 = gamepad, P2 = half of keyboard -- İnput Actions = "Player" and "player2"
P1 = half of keyboard, P2 = gamepad -- İnput Actions = "player1" and "Player"

How can I do such a control scheme when my second character is spawn? How do I find connected gamepads? and how can I adjust the control scheme of the second character to the keyboard by instantly removing the second gamepad? Thanks in advance
