From the EPSG4326_500m  tile matrix set:

<TileMatrix><ows:Identifier>0</ows:Identifier><ScaleDenominator>223632905.6114871</ScaleDenominator><TopLeftCorner>-180 90</TopLeftCorner><TileWidth>512</TileWidth><TileHeight>512</TileHeight><MatrixWidth>2</MatrixWidth><MatrixHeight>1</MatrixHeight></TileMatrix>

<TileMatrix><ows:Identifier>1</ows:Identifier><ScaleDenominator>111816452.8057436</ScaleDenominator><TopLeftCorner>-180 90</TopLeftCorner><TileWidth>512</TileWidth><TileHeight>512</TileHeight><MatrixWidth>3</MatrixWidth><MatrixHeight>2</MatrixHeight></TileMatrix>

<TileMatrix><ows:Identifier>2</ows:Identifier><ScaleDenominator>55908226.40287178</ScaleDenominator><TopLeftCorner>-180 90</TopLeftCorner><TileWidth>512</TileWidth><TileHeight>512</TileHeight><MatrixWidth>5</MatrixWidth><MatrixHeight>3</MatrixHeight></TileMatrix>

<TileMatrix><ows:Identifier>3</ows:Identifier><ScaleDenominator>27954113.20143589</ScaleDenominator><TopLeftCorner>-180 90</TopLeftCorner><TileWidth>512</TileWidth><TileHeight>512</TileHeight><MatrixWidth>10</MatrixWidth><MatrixHeight>5</MatrixHeight></TileMatrix>

You can convert the ScaleDenominator to resolution with `mapproxy-util scales`. For example:

% mapproxy-util scales --as-res-config --unit d 223632905.6114871 111816452.8057436 55908226.40287178
    res: [
         #  res            level     scale @90.7 DPI
            0.5625000000, #  0   223632905.61148709
            0.2812500000, #  1   111816452.80574360
            0.1406250000, #  2    55908226.40287178
    ]


So something like the following should work:

grids:
  EPSG4326_500m:
    bbox: [-180, -90, 180, 90]
    srs: 'EPSG:4326'
    tile_size: [512, 512]
    origin: ul
    res: [
         #  res            level     scale @90.7 DPI
            0.5625000000, #  0   223632905.61148709
            0.2812500000, #  1   111816452.80574360
            0.1406250000, #  2    55908226.40287178
	    .....
    ]
