can i updte text on tkinter without interacting with the ui? (using as a display only)

Here is script:

import tkinter as tk
import RPi.GPIO as GPIO

# Setup GPIO
GPIO.setmode(GPIO.BCM)
button_pin = 18   
GPIO.setup(button_pin, GPIO.IN, pull_up_down=GPIO.PUD_UP)

def check_button():
    if GPIO.input(button_pin) == GPIO.LOW:  # Button pressed
        update_display()
    root.after(100, check_button)  # Check every 100 ms

def update_display():
    # Update your Tkinter display here
    label.config(text="Button Pressed!")

root = tk.Tk()
label = tk.Label(root, text="Waiting for button press...")
label.pack()

# Start checking for button presses
check_button()

root.mainloop()
