My friend tried it and it didn't work. Two people told me that the code must be written to remove a field or just make it optional
Of course, only in the address form when ordering from the store. As for the contact us form, the matter is easy, of course

Hello this is Gulshan Negi

Well, I searched about it on Google and I found that if you are using Odoo Studio, you can also follow a similar process to modify the fields of the address form:

1. Log in to your Odoo instance and navigate to the website module.
2. Go to Configuration > Website.
3. Click the "Edit" button next to the "Checkout" page.
4. Click the "Edit" button next to the "Address" form.
5. You can drag and drop the fields to rearrange them as desired.
6. To make a field optional, simply uncheck the "Required" checkbox next to the field 。
7. Click the "Save" button to save your changes.

I hope it will help you.

Thanks
