When you use highlightbackground you need to provide a color code, for example "#37d3ff". So use highlightbackground="COLORCODE" and remove relief="solid"

For example:

import tkinter as tk

root = tk.Tk()
root.geometry("800x450")
root.title("How should i change border color")
tk.Label(root, text="How should i change border color", width=50, height=4, bg="White", highlightthickness=4, highlightbackground="#37d3ff").place(x=10, y=10)
tk.Button(root, text="Button", width=5, height=1, bg="White", highlightbackground="#37d3ff").place(x=100, y=100)


root.mainloop()

result:

Update: While it workes on my ubuntu machine, I just checked it on windows and it doesn't work there.
