I'm getting
CompilerError: Stack too deep. Try compiling with `--via-ir` (cli) or the equivalent `viaIR: true` (standard JSON) while enabling the optimizer. Otherwise, try removing local variables. this error. According to solidity docs I need to add "viaIR": true option but I can't add the same option to the brownie-config.yaml file. Here is the file: compiler: viaIR: true solc: version: 0.8.17 optimizer: enabled: true runs: 200

If after using the viaIR it still fail then it is likely the contract is still too complex.– Ismael ♦Feb 9 at 3:27

Add viaIR to your brownie configuration (only on master branch of brownie at the time of writing)
$> cat brownie-config.yaml
[...]
compiler:
solc:
# viaIR option has been added in 0.8.13, you can adjust the version your need
version: 0.8.13
viaIR: True
