While Wi-Fi is disabled, auto-join for any nearby Wi-Fi networks is also disabled until:

- You turn on Wi-Fi in Control Center.

- You connect to a Wi-Fi network in Settings > Wi-Fi.

- You walk or drive to a new location.

- It's 5 AM local time.

- You restart your device.

Depends on what you call disable. Tapping in the control center will disconnect from WiFi but the phone will then connect automatically to any other network it knows.
