Using this python library (I am the author)
>>> from cryptotools import PrivateKey
>>> prv = PrivateKey.from_wif('5KUkQNKHA9cVmhSyKuNmop7r83DN2fMhPtNUW843Q6JxqRddEVz')
>>> prv.hex()
'db07a0c6c98c7a2b5cdc19cd4431a05908a40424d6d1ff20eac9cb2f9488e12d'
If the key is too large
>>> PrivateKey.from_int(1 << 260)
it will throw an error
AssertionError: Key larger than Curve Order

No. If you have a number that's too large you should first find it's congruent modulo N and then import that– Mike DJul 8, 2021 at 18:07
There is also a bash (or zsh) shell script to convert from WIF to hexadecimal format: https://gist.github.com/GregTonoski/fbe2740391a366add4bfcefded00c5c4
Simply run the script like in the example:
$ bash Bitcoin_WIF_into_hex.bash "L3wB8ytuxNS3SPX2CJnHqK48Zzqj1AnayDTrJomvNPDxuKvHyvpT" > private_key_bitcoin.hex
