Can i ask ACS to change my current employment end date?

Could I ask ACS to change my current employment from (01-2014 to 02-2019) to (01-2014 to currently employed) or do they always put the date of ACS skill date as end date ?

ACS will not change your current employment’s end date on request

The date mentioned on your current employment’s work experience letter is considered the last date of employment as per ACS rules.

Keep Current Employment end Date blank in EOI

You are allowed to keep current employment’s end date BLANK in your Australia EOI.
