Not from within Resolve, no. This is a hard thing to estimate, particularly with variable bitrate codecs, because a lot depends on the complexity and runtime of the picture (and sound).

The workaround I use is a) I use an external app like Video Space calculator and I manually key in the program time, resolution, frame rate, codec, and so on and then look at what its estimate is:

and b) I have big mofo drives so I never run out of space. I have one specific drive called "Render Drive" that we use just for that purpose, and I clear it out every few months so it has terabytes and terabytes of free space. Once the file is rendered, I'll check it and see specifically where we're at in terms of file size.

For those who might prefer it, a version of Video Space Calculator is also directly accessible on their website: https://www.digitalrebellion.com/webapps/videocalc

If you plan on dipping much UHD video work at high quality levels - high quality ProRes or the like, you will need lots of big drives think 10s of TB. There are enough challenges without attempting to save disc space.

If you really cannot get the drives you need, work out a low resolution proxy workflow, and go full res on delivery. You will still need big enough drives to store your originals + the proxies..

Getting the best out of a given file size is the point of multi pass encoding. Research that for your particular codec.

Thank you so much, I´ll try the calculator you mencioned! In my case, I need to know the size because some clients tell me they need some particular size ("Around 500MB" and so), is not a hard drive space problem! Thanks!
