Just add the variable stop and if stop == True then the clock will stop

Solution to your Question

import tkinter as tk
from tkinter.constants import *

def start():
    global hours, minutes, seconds, stop

    if hours == 4:
        return
    if stop == False:
        seconds -= 1
        
    if seconds == 00:
        stop = True
    
    elif seconds == 00 and minutes != 00 and hours != 00:
        minutes -= 1
        seconds = 60

    elif minutes == 00 and seconds == 00:
        hours = hours+1

    clock.config(text=f'{hours:02}:{minutes:02}:{seconds:02}')

    root.after(1000, start)

root=tk.Tk()
clock = tk.Label(root, font=("bold",20), anchor=CENTER, text="00:00:00")

clock.place(relx=0.5, rely=0.5, anchor=CENTER)

hours,minutes,seconds,stop = 0,0,5, False

start()

root.mainloop()
