What you can do is issue credit notes in respect of such invoices and file in the gstr 1 of the next month. in this way the effect of invoices becomes nil

Nothing can be amended in GSTR 1 once submitted (though not filed)..
Have to know the reason for requirement of deleting the invoices to comment on appropriate solution..
