Depends where the grinding noise is coming from. If its the box itself, then the only band aid fix I could recommend would be Redline Shockproof from BNT etc. Could be a mis-aligned clutch plate, worn synchros etc etc. Possibly even ring gear.but I am quite pissed so take everything I say with a grain of salt;)

G/boxor transfer box bearing(s) if only under load,can't be ring gear or syncros or miss-aligned cl plate

My first thought was release (thrust) bearing!

Input shaft bearing, its takes most of the load, its box out & partial disassembly ,to replaceif it was the clutchthrust it would be worse when depress the clutch .

Most likely a clutch thrust bearing. If it were an input shaft bearing you can test for wear by loading engine up in third gear steep grade. Dont let it rev but load in low revs in third. If you hear the same noise it is the first motion shaft bearing. Require gearbox removal.
If its only when depressing clutch I would not worry too much as it is rare for them to fall to bits.

doesnt a stuffed thrust bearing make noise with the clutch pressed down and stoppes then you let the clutch out! input shaft does opposite!

All the noisy clutch thrusts I've known have been noisy whenever the clutch is in, (regardless of whether you are in gear or in neutral) and the noise stops while you have the clutch pushed out.But then, none of these have been FWD Toyotas!
We are told this noise is not present at idle while stationary, so could it be a countershaft or output shaft bearing!
