You mean during the kingship? Not that I'm aware of, although there may be something I'm forgetting. Traditionally the Sabines settled on the Quirinal (hence its name), and we know archaeologically that there was an early settlement there. In the historical period the Quirinal was closely associated with Sabine settlement and was the location of a number of temples to native Italian gods, especially the Sabine deities Quirinus and Semo Sancus. The Aventine was associated in tradition with Remus, and though foreign gods, such as Juno Regina, often had their temples established their by virtue of its location outside the pomerium I can't remember ever hearing of an association with the Sabines. If anything it was associated more closely with the Latins, towards whom it pointed (it would be a bit bizarre to expect major Sabine settlement in the location furthest from Sabine country), by virtue of the establishment of the temple of Diana, who symbolized the Latin League. But the Aventine's strongest traditional association was with the secessio plebis, since during the Conflict of the Orders the plebs camped out on the Aventine. As late as 121, B.C., over a century after the end of the Conflict of the Orders, the Aventine was still seen as the traditional site for secession. Certainly during the historical period there was no major Sabine settlement there, since the hill was actually part of the ager publicus from 456 and was from an early date what the OCD calls a "cosmopolitan centre" rather than one dominated by a particular group
