Sram Red chainrings

Hi I have a Altamira sram red 11 speed with 53/39 chain can I replace with a 52/36 chainrings ?

No, You have a 'standard' chainset (39/53t) which has a 130 BCD (bolt circle diameter). The smallest inner chainring you can put on is a 38t.

You can change the 53t to 52t but there isnt much point.

Those 52/36t rings will be for a 'compact' chainset with a 110 BCD.
