There is plenty of aftermarket options that bolt into that factory bolt in the tray that look great and are super sturdy. I have one from BulletPoint and it’s been rock solid even on high speed desert runs - phone doesn’t budge.
The radio mounts right under that and the plastic is not very thick like @DirtHeadDavis said you’d be better off with a mounting solution like bulletpoint it’s also what I run on mine and it’s solid
As you can see here where I drilled the hole in mine to power my phone charger the radio is right under it
