When using swr cache routing in the default server nitro in nuxt3, how to specify the name of the generated cache key?

This is my nitro configuration

export default defineNuxtConfig({
    ssr: true,

    nitro: {
        routeRules: {
            '/': {
                swr: 7200,
            },
        },
        storage: {
            cache: {
                driver: 'redis',
                host: 'localhost',
                port: 6379,
                db: 0,
            },
        },
        devStorage: {
            cache: {
                driver: 'redis',
                host: 'localhost',
                port: 6379,
                db: 0,
            },
        },
        externals: {
            traceInclude: [],
        },
    },
})

I get redis data with key name nitro:routes:_:index.il7asoJjJE.jsonredis db
