Process strawberries in food processor until smooth, about 30 seconds (puree should measure about ¾ cup). Microwave sweetened condensed milk, white chocolate chips, and vodka in large bowl until chocolate melts, about 1 minute, whisking halfway through cooking. Whisk in strawberry puree, vanilla, and salt.

Using stand mixer fitted with whisk, whip cream on medium-low speed until foamy, about 1 minute. Increase speed to high and whip until soft peaks form, 1 to 3 minutes. Whisk one-third of whipped cream into strawberry mixture, then gently fold in remaining whipped cream, 1 scoop at a time, until combined. Freeze in airtight container until firm, 6 hours or up to 2 weeks. Serve.
