You can define a custom style and from their change the font option, this is a sample code to change it:

import tkinter as tk
from tkinter import messagebox

root = tk.Tk()

# Define custom style
style = tk.ttk.Style()
style.configure("CustomMessageBox.TLabel", font=("Arial", 14))

# Show messagebox with custom style
messagebox.showinfo(title="Title", message="Message", icon="info", parent=root, style="CustomMessageBox")

root.mainloop()
