Sybase (sql anywhere 17) / ODBC connection for writeback

[lgpower]

Hi, 

I have a local sybase sql anywhere 17 database that I want to write data to. 

I have an on premise data gateway set-up with both the Sybase data connector and an ODBC connector where dsn=sybasedriver. 

Also in powerapps dataflows I am able to retrieve data using the power query ODBC connector  and save it in CDS entities. 

Do I have any possiblity to write back to my Sybase db within powerapps using patch functions? 

With kind regards,
