Preheat the oven to 180°C (356°F) with the fan on. Line a 9-inch (23 cm) cake tin with baking paper.
Pulse the graham crackers in a food processor until finely crushed. Add the dates and pulse until the mixture holds together when pressed.
Press the cracker-and-date mixture evenly into the bottom of the prepared tin. Bake for about 15 minutes or until slightly golden, then remove from the oven and let cool.
Soak the gelatin sheets in cold water until soft, about 5 minutes, then drain and squeeze out excess water.
Warm the canned coconut milk in a small saucepan over low heat. Add the softened, drained gelatin and whisk until fully dissolved; do not boil. Remove from the heat once dissolved.
Combine the vegetable cream cheese, powdered sugar, and the warm coconut milk with dissolved gelatin in a blender or food processor. Blend until smooth and fully combined.
Pour the cream mixture over the cooled crust, smooth the top with a spatula, then refrigerate the cheesecake overnight (about 8–12 hours) until set.
Decorate the set cheesecake with strawberries and edible flowers just before serving.
