You can uncheck the 'shipping address' field on the sales forms from the custom form styles.

Click the Gear (⚙) icon at the top > Your Company > Custom Form Styles > Under Action column, select Edit > Go to 'Content' tab' > Click the 'pencil' icon at the top right corner > Under 'Display' at the bottom, you should see 'Shipping' field > Uncheck 'Shipping' field and click DONE.

Hope this helps!
