Update read only entity using Non-Admin user - When Quote is having active status

Hello Community,

I have one scenario where I need to update quote entity's one field when quote is having active status.

For this I have written Jquery to update record, its working fine for Admin user but not working with Non Admin user.

I have given full write access for Quote entity but still I am not able to update field.

Any solution/suggestion will be appreciated.

Thank you,
