No you can not do data transfer on ASA using VPN only phase 1. For data transfer on ASA using VPN there must be both phase 1 and phase 2.
I am glad that my first response was helpful. It is not possible to have data transfer on ASA using VPN with only phase 1 because the Security Association that identifies the encryption of data that protects the data in IPsec is negotiated in phase 2. In the phase 1 the ASA is negotiating the working keys that will be used but does not negotiate the encryption parameters until in phase 2.
